Fiberglass repair

[Cbridgewater]

Have some damage to my 72 challenger grill. Suggestions on repairing?

The crack is easy - drill a small hole at the end of the crack which will help stop it going any farther, grind out the crack to a "V", get some fiberglass mat and resin/hardener and cur some small pieces and fill it in. Make sure there are no air bubbles in it, use a small acid brush or special roller to do that. I`m sure there are plenty of tutorials on You Tube for this. The missing section is basically the same but you will need to make a "mold" to keep the shape till the glass cures, there are a bunch of ways to make one and you can use wax paper between the mold and glass so it won`t stick and release easy.

There is a fella in Denver whom I was friends with.  Drew.  He is a dentist and would use a special dental glue for repairing the plastic grills.  He repaired a 71 lower valance for me and it was one of the best repairs I have seen.  Not sure exactly what the glue was, but it was a special dental glue.  I believe it was used for crown's or caps.

If possible use Epoxy resin instead of polyester.  Mush stronger and no shrinking. Won't draw back into the repair.
