I’ve avoided doing body work so far but the time has come to learn.

Kinja'd!!!

Bought it this way, haven’t found another AMG bumper for it so my question for you is, can I save it?

Cracked in the thinnest parts so getting strength in there may be hard. Tired of it looking like it has a split lip.

Weather is nice now and it is time to start this years projects!

PC + PBT Xenoy (Polycarbonate blend), from what I understand this makes it harder?

Not sure. The airless kit that I borrowed from my local parts store had several different kinds of rods in it, for the different varieties of plastic out there. I’ve only used it once, though, to patch up a broken fog lamp housing.

Option 1 - Weld it
Option 2 - Go to dealer and get new bumper
Option 3 - Check junk yards for replacement bumper
Option 4 - Zip ties
Option 5 - Gorilla Tape
Option 6 - Save the money and live with it
Option 7 - Get a different car

That’s all the options I can think of right meow

From the photo, it looks like you should be able to add fiberglass in the back to bridge the gap and add structure. Then use filler in the front to clean things up. You may want to apply glass fiber reinforced filler for better structure before a top coat of standard plastic filler.

I’d look for another one. This is a difficult repair for a professional, let alone diy. Plastic welding can work but it’s tough finding the right rod, which sometimes still won’t work because there is simply not enough strength in the repair. They make excellent epoxies now for bumper repair but the shit isn’t cheap and you usually need to buy the gun type tool the product inserts go into then mix in the exit tube...adding expense where a good used part would possibly cost less or slightly above.

source: I’m a professional, I wouldn’t take this repair on for two reasons. A) Time consuming and degree of difficulty B) If you repair that it’s going to be weak structurally and will have high failure potential. Think it looks bad now? See a tapped repair fall apart.

Hot staples. This is the exact kit my shop uses:

This and a little flexible filler and you’re good to go

This is the cheapest stuff I could find that was a legit product for repairing plastic. http://www.eastwood.com/ew-2k-universal-urethance-adhesive-cartridge.html

using the above tape and the adhesive the tape is a fiberglass mesh that embeds into the tacky adhesive and then more adhesive used on top of it and really strengthens a repair. lots of bumper things can be repaired such as replacing missing tabs fixing cracks etc.

Your first step is to figure out what plastic the bumper is made from and that will determine the repair procedure and adhesives and crap that can be used.

Here is a good article to get you started and see how its done

http://www.hotrod.com/articles/ccrp-0904-how-to-repair-your-plastic-bumper/

Also check out 3m training type videos on youtube.

Mercedes should have a body repair manual that describes proper repair procedures and show what materials are used on parts of the car the one for my miata shows types of damage to the plastic bumper and suggestions on how to fix the crack or if the crack is too long to just replace the bumper etc.
