Glueing Plastic Fender Well Parts
MY 2000 C5 and I hit a tire wall at turn 8 Summit Point last October ( probably need more skid pad time.)
Due to a back operation, I was side lined for some time. At any rate I'm back in the groove and am dying to be tearing nose, LF fender, and LR quarter panel off because they are fractured. I have replacements and have to sand and paint these. Here's my question: the black plastic fender wells or wheel wells(LF and LR) have some fractures in them. The LF fender wheel well has fractures just below the triangular headlight bracket. I would rather NOT remove these but would like to use some epoxy and fiberglass matting and sandwich the wrinkled black plastic in order to make the repair. I'm thinking of making a form or template from plywood from the undamaged right side. Then coating it with wax or something similar, attach it to the LF w/ 1/4-20 screws, then glue and laminate the front side, remove the template or form then do the same on the back side. I'm not looking for pretty, I'm looking for sturdy. Anybody do this before? What epoxy is compatible on the black plastic fender well? JB weld? 5 Minute epoxy?
Bottom line is I would rather not replace the fender well for about a crunched 12" x 15" section.

I had a crack at the top of the fender in the inner liner as well as some busted up headlight area in my race car last year. I just used thin cardboard and taped it with slick packaging tape to make it slick, duct taped it in place/shape then used fiberglass mat and resin from Home Depot and it worked great. A little sanding and grinding after and like new!

Drifting
drill the ends of the cracks. That'll keep em from spreading. Get yourself a vac pump and some vac bagging supplies and sandwich the part with a few layers of fiberglass weave wetted in with a good epoxy. Then add your release film and absorber mat, shrink the vacuum down on it and call it good.

Just use an aluminium plate and splice the crack.

Melting Slicks
Bolt on your LF fender, LF headlight/cover and front bumper and check your alignment before repairing the crack. Then rivet them in place and remove the fender, light and bumper. Finish like the others have said. This will both form and function.
