I have found a couple cracks in the plastic callouts on the hood. What is a good repair for these? There are three attaching studs that have twisted out of the plastic that need repair too. Perhaps epoxy some studs in?

I had some damage to my air grabber door - which I THINK is made of the same material. While they weren't cracks, they were areas where the material has gotten soft and deeply pitted. I used plain old fiberglass epoxy and it seems to have made the repaired areas stronger than the original, and has bonded well.

If it were me - I would put some fiberglass epoxy and matting on the inside first to reinforce the area good. Probably several inches on each side of the cracks. On the outside I would dremel out some narrow channels to widen the cracks and fill with fiberglass epoxy, then sand smooth.

make sure you drill a small hole at the end of the crack too....that will keep it from growing
