Can any guide me in the right direction here? Stripping the paint from this ‘77 630 csi hood, and am wondering if this is safe.

Just scuffing it up enough for primer to stick. Is the mask pictured adequate protection? Or do I need something better? As you can see I’m about halfway done with the underside, it’s not going to be perfect, as this is for a project I’ve got going on, but don’t want to modify original body panels. Also it’s got some rust so don’t behead me when you find out what the final product is. ;) just know it will be mad JDM, yo. (No I am not putting a flat black or rusted hood on my car, that would look like garbage. Think more along the lines of ”shakotan”)

Who said rust had to be ugly? Sure is interesting looking.

Starred for the car and the rust photo, have absolutely nothing to contribute.

Well thanks anyway! How are things in the Zoidberg household? Puppy hasn’t chewed up anything in the Celica I hope? :p

Get a carbon fiber hood to replace it.

In spite of the pup’s best efforts, I have managed to preserve the Celica’s interior. I was wise to buy another cheap car instead of something “nice.” My dog happily owns the backseat and I don’t give a crap.

Hey now! Cheap cars can be nice with a little elbow grease as I’m sure we’re both well aware ;) would rather have a 3k celica than a 10k camry, that’s for sure! Besides, we all know nothing is safe from puppy teeth. NOTHING! MUAHAHAHA.

Mask in photo is not adequate. Better then nothing, but get a paint/particulate mask. $25 at home depot. They have replaceable filters and with good cleanliness, wiping out the condensation that forms on the mouth piece and cleaning with a good non toxic solvent on occasion it will last a long time and your lungs will thank you for it.

We had a guy that said he hadn’t smoked in the last 20 years, I looked at some cells from his lungs and you could still see evidence of carbon deposits in his cells. Shit that goes in your lungs stays there and continually contaminates any new cells, don’t mess screw around.

Treat the rust with some rust converter, it is going to continually rust, but you can slow it down and cut off the supply of oxygen and if you are lucky you won’t notice it coming through the other side.

For scuffing make sure you take special care with a brush of that nature, it is going to leave streaks in the paint that unless you go real heavy with the next coat it will not cover up. Use a scuffing pad if the paint is in good condition, if it needs to go deeper use a rough sand paper sponge or emory cloth less then 100 grit, then work up to about 400 grit. Make sure to give the thing a good wipe with a wax/grease remover after you are done, and make sure to put down a painting sheet or some thing for the surrounding area if you are using spray cans, the particles will fly much further then you think. A fan can help in that regard by pulling air away if you are in an enclosed space.

Be safe! Post pictures!

I have a feeling a rising sun is going on the top?

Many thanks! This is why Oppo is my car site of choice. You’d have to pay for advice like this elsewhere!

I had a feeling this was not adequate protection, and also why I stopped halfway. I don’t often strip paint, but I do smoke (not cigarettes. Dont worry im in oregon it’s legal) and I’d like to do everything I can to keep my lungs healthy (ironic I know, I know). The underside will likely be left primer as nobody will see it anyway, I have color matched paint for the top.

See my other comments for what my plans with this hood are. And I will of course be posting pictures upon completion!

Again thanks mate!

“The dose makes the poison”. The risk in stripping or grinding is the volume of substance you inhale and over what time. Too much, or too quickly, or too powerful a substance, and you’re in trouble. The unknown piece here is what’s in the however many years old paint, and that likely that substance was never tested for long term exposure or effect. So, what you want to do is minimize your time and dosage. The mask you have does help, quite a lot. But it is not a good seal against your nose and mouth as compared to a proper mask. In other words, you’re likely inhaling a significant non-zero amount of sanded particulate from that hood. Additionally, particulate masks don’t do anything for chemical vapors. I don’t know if that’s any part of your project (like chemical strippers, VOC sprays, and so on). Try getting a good rubbery mask that seals well and has replaceable filter cartridges. They’re at most hardware or DIY home improvement type places. Check the paint and Safety sections first, but you can also check out the Drywall aisle, too. If you use a chemical stripper, be extra cautious; the regulations around those substances and the warnings about how hazardous the vapors can be are quite weak.

I do like centerlines but nope, it’s Borbets, mesh, or turbines for this one. Need new (smaller) tires to run turbines unfortunately, probably with some stretching. No negative camber though.

No chemicals this time!

Again, I’ve got to say many thanks! I’ve been unable to find out if the paint is lead based or not but I’m assuming it is because ‘77. The BMW 6 series page just laughed me off as being a millenial. Oh well, I’ve got other, better resources apparantly!

This is why I like this site best. Good honest answers, without the bullshit. I will be making a trip to home depot for a better mask tomorrow.

Thanks again!

Sure thing, I happened to know just a bit about the subject so I figured I would chime in. Listen to that voice, it can really save your health!

Remember primer is primer, think about that word. It is for use before paint. Some primers are even sticky in that regard, that tends to be why cars that are primered and driven usually have to be re-sanded and primered prior to paint. I would throw a cheap automotive enamel on, even if it is just spray paint it would make it so that it doesn’t turn all gummy and yucky.

Just as a side note, It’s legal up here in washington too and you are still inhaling quite a bit of crap, the only benefit is that hopefully you don’t smoke as much as you would with cigarettes. This is strictly from a science perspective, people have agenda’s for citing studies, either pro or against. Personally I have respiratory problems and I get enough crap from painting, sanding, welding, exhaust fumes etc, even with a respirator that it really doesn’t need any help from other sources. If it is what you enjoy then do it, it used to be a terrible myth when I was younger that it was “healthier” then cigarettes. Honestly the truth is in the same quantity I think you would be hard pressed to say one is healthier, just one is going to be not as bad.

Ah, fender mirrors, I put them on mine and boy they look good, but are hard to look out of. You seem very knowledgeable, but just a small word of warning, make sure the template if you are following one is converted for the correct orientation of the steering wheel. A few members off of my car’s forum took instructions from Australia and found out too late.

More good suggestions! Again thank you! I may clear coat the bottom, I just don’t want to paint the underside because if I do end up selling my car, I’m keeping this hood and likely buying another (hopefully silver-blue, bright red=attention, which is nice sometimes, but usually not so much so) e24, and wouldn’t want to strip the bottom’s paint twice.

And don’t worry I agree. Smoke is smoke and isnt good for you in any way. However, since I grow my own (far outside city limits and contamination) I’ve got to think it’s a *little bit* better than the tars and other things added to nicotine sticks. Plus I don’t drink too too often so it’s my only vice for now. I also don’t really do things like this (paint work) often. Mostly for myself only.

Again your thoughts are most appreciated! Good to see another open mind on Oppo!

I usually only use my rear view for looking behind me. I won’t lie, this is mostly just for looking cool ;) I also appreciate the kind words! I try to keep my online presence very tidy. Too many people my age make us look bad. I promise we're not all dummies!

Glad to help! The corollary saying is, “The solution to pollution is dilution”, so be sure your work area is well ventilated. Easy enough, just open the garage door, or run a fan through an open door just to get some air flow. If you use a kleenex after working and get a Pollack canvas imitation (colors and spatter), your breathing protection was insufficient for sure. Good safety gear, for amateur level occasional use, is just not expensive anymore. In other words, a good mask costs far less than the hood and materials for your project, it’s very near rounding error for the budget, and you can re-use your safety gear for many future projects (drywall, auto interior refinishing, floor refinishing, attic or insulation work, crawlspace work, and so on). I’ve had a good 3M mask with a cartridge system for 16 years, just replacing the filter bits as needed and it works nicely. I like mine because the particulate filter is before the chemical (activated charcoal and some other stuff) pack, so I can replace one, the other, or both as necessary. In a professional setting, that might be too frequent for the cost and something like a sealed system or positive pressure respirator would be better, but for amateur garage work it’s quite nice. Post pics of the finished work! Looks like a very nice piece of bodywork!

You have come seeking opinions and are open to suggestions, I think that is about the best things possible and something I hope I never lose. I had to resort to a wider rear view mirror so that I don’t have to rely on the fender mirrors as they were useless other then when the car behind was a really flashy color or it was late at night and I could see light being reflected, so far forward and with stiffer bushings all I see is a blur pretty much, if you have been doing the same and relying more on the rear then not much difference I suppose.

Put masking tape over where you are drilling to prevent chipping.

Just a thought, but would media or soda blasting be an option? It can be a risk on hoods, what with a huge surface area and the possible heat distortions (sand blasting gets really hot), but it can be a big time/labor saver with all the cross bracing and gussets. FWIW, my main hood stripping experience is a ‘78 280Z. Straight six with a very long hood. And an ‘80s Toyota pickup where it was such a mess that a new piece was a better choice (not really an option for you, I think). Anyway, really look forward to seeing your progress!

Don’t use chemical strippers it will get all up in those crevices and then paint will never stick and other terrible things like more rust forever.

make sure the mask is a good one or ones because some are just for dust and pollen and crap. I think body shops use N95 or P95.

If the lug pattern matches, and if you can find them for less than a small fortune, E34 M5 turbines would look super cool on it.

My recommendation (this is definitely different than normal Oppo stuff) get a vape. Don't have to deal with smoke, doesn't leave any smell at all, and it doesn't give you any dry mouth. My personal favorite is the FlowerMate V5 Pro. You can vape it, and then you can turn the leftover vaped material into some very potent butter or oil. Nearly doubles the amount you can use.

Since I’m in Indiana, I’m obliged to say that I don’t partake myself. I totally only know this through second hand experience. :)

That's gonna leave a mark! > Sovereign, Purveyor of Coupes 06/04/2016 at 06:16

Generally lead is not an issue for automotive paints however there may be a number of other things in it to avoid. BMW doesn’t make the paint and has no idea what is in it as the formula for the various layers of paint as it is propriety. You will not get a formula from DuPont, Akzo or other automotive paint manufacturers, besides many have been bought out or closed since 1977.

BolderZ has given you good advice on handling.

Unfortunately not really. The cost of blasting would exceed the cost of the hood paint and mirrors combined, not to mention it was from an earlier Karmann-made model where rust proofing was non existent, so likely it would gum up the metal pretty bad in areas that are rusting.

Keep your area very, very well ventilated. I always have a fan pointing at my face when doing this to keep the dust away from my lungs. You also might want to wear ear muffs because the sustained volume from grinding is actually alot. People don’t care enough about their ears until it’s too late.

Oh, that’s a bummer. Alternatively, that could be a great candidate for some of the newer laser rust removers, but I don’t know of any auto shop that has one. Still a bit cost prohibitive, it seems.

Single coat or cleared? Seems like most 90s cars had paint longevity issues. I have yet to own a car with a nice paint job.

I know that some GM vans shed their paint especially. I’ve been told that it’s UV going through the top coat and attacking the primer, and I’ve been told that some cars sat overnight on the assembly line awaiting paint and the primer lost its zeta factor and the top coat wouldn’t stick as well.

The second one doesn’t surprise me too much. I’ve made that mistake before, except never on something as big as a new cars paint job.
