Repairing the urethane bumpers
Once I got the bumpers and ground effects sanded, I realized that some were in need of repair. Here again, the heat gun worked wonders to get the warps out. But for tears and splits, I used a product called "SEM ure-weld". Its a 2-part mixture. It bonds with the urethane at the molecular level. It really works(when the directions are followed)!
Heres some pictures of fixing the worst tear. It had been repaired before at some point. But it was not done correctly. Ure-weld was used, but the back was not cleaned down to the urethane, therefore it did not adhere correctly. And there was no mesh(screen) to reinforce it. I could also tell that the bumper cover was not removed to do the repair.
It was quite a mission just to do this one repair, and I had several more but they were'nt as bad. The area above the exhaust exit had to be nearly completly rebuilt, as it was dried out pretty bad from the heat. And I made a nice stainless steel heat shield to replace the old one.
Overall, the repairs turned out great, and seem as strong as new.
These are before pictures. Notice the zip-tie holding the 2 sides together.
Frontal views. The one on the right is after some grinding away of the old repair.
The left picture is after grinding the inside. The right is after cleaning and gluing the 2 halves together with loctite 101(super glue). Grind away a little valley in the joint on both sides. Leave just enough glue to hold it together.
Use some window screen for reinforcement on the back. Hold it in place with a few dots of super glue. Slather the ure-weld over and down into it. It gets hot when its taking hold. Do the front side too, just don't over-do-it.
It sets up FAST! Two half-dollar size blobs is enough to work with. You gotta be quick, and don't mix a lot at one time. The stuff is a bit pricey, so use it carefully. Then sand it and shape it using progressivly finer sandpaper. That it! Primeable and paintable.
