Had a few minutes and decided to use the one frame horn (which has been bruising my shins at every available opportunity) to experiment with how I’ll be removing the old undercoating from the Chevelle’s frame and prepping for paint .

Starting with a small section on top, I developed a plan which I then applied to the whole area. First: the <$30 harbor freight “mini needle scaler” (which I didn’t know existed until it was on the front page of a catalog I was throwing away!) does a great job of removing 40 year old rubberized undercoating. Hopefully it holds up to doing a bunch more.

Ignore the shiny top, it’s had more done to it. Just the area (on the sides) ahead of where the tool is laying has been de-undercoated.

Next up a stripping wheel on the die grinder made short (and dusty) work of removing surface rust and generally prepping the surface for finishing.

Currently drying is the test to see if I can brush on red primer and have it lay flat enough to be okay, or if I’m going to have to spray the primer. I plan on spraying the satin black topcoat when all is primed, but for doing little bits at a time it’s pretty convenient if I could brush on the primer (not looking feasible, though).

And now I realize that I really need a needle scaler. The rear subframe and structure of my Camaro needs a serious cleaning/ going through and I was dreading getting in there with a wire wheel and brush. Once I drop the gas tank one of those would be perfect for the job.

I would be hesitant to use it on sheetmetal but for heavier stuff it works nicely.

Yeah, definitely not for sheetmetal but much better than scraping and wire wheels on frames and such especially if there’s undercoating involved. Speaking of which, do you think it would be good for floorpans?

If you got a large area, rolling the project outside and paying a mobile media blaster guy to do his thing for an hour or two is a fantastic investment.

Hmm, I’m not sure. I intend to try it on an out-of-sight area of the firewall at some point here (though it’ll be a while). I’m not sure if it would notice ably dimple the metal or not

Always wanted to try one of those needle scalers. N ever even noticed that HF carried them until Uncle BF posted this:

That’s the one! I didn’t know it existed until about a week or two ago when I got one of their fliers. While transporting it from the mailbox to the trash I happened to look at it and notice the mini needle scaler, which struck me as potentially useful for this. With the 20% off, it was like $25 so worth finding out!
