What is under the paint on my hood? (Page 2/2) Tha Driver OCT 28, 03:33 PM What you need to do is first sand off all the paint to see if there are other areas like this. Then, grind out all the non-factory filler including the resin with a 24 grit disc & see what's under all that. If it's really deep (& only in that one place), fill it using SMC compatible resin & fiberglass mat, using a roller to smooth it out & remove the air bubbles. Grind that flat with 24 grit & smooth out with 'Vette panel adhesive/filler. If it's not too deep, just smooth it out with the filler. If it's widespread damage, find another hood.
