bumper 5 Years, 1 Month ago Karma: 0  
wie weet van welke materiaal de voorbumper gemaakt is ?
ik wil die van mij gaan herstellen maar moet weten uit welk materiaal deze zijn gemaakt zodat ik weet dat ik met glasvezel kan werken of niet.

groeten

The bumpers are RIM: Reaction Injected Molded Urethane. You can buy a two-part repair that dosen't require a "welder". SEM part # 39708 works well.
I've posted this before - a search should have turned it up:
You'll want to "V" out the tear with a small grinder using a 24 grit disc. Grind slowly so as not to melt the material, as that will close the pores & cause the repair to not stick. Best to grind the back too (but not "V" it) & chop up some fiberglass mat with scissors into 1/4" strands & mix with the repair material. Build up an area about 1" beyond the tear & at least 1/8" thick. Once that dries do the "V" in the front & fill that; 'glass strands not required but will add strength. Grind/sand/finish down to a final grit of 180, prime with epoxy primer. The epoxy primer is flexible like the bumper. Paint as you would any body panel.
