If you're talking about and old Vette C1 or C2 and early C3, then the gelcoat is there and seals the glass, but again, modern epoxy primers will seal it just as well. No need to deal with gel coat unless you have an old Vette and you're into originality.

Gel coat is like peanut brittle.... in 50's corvettes body panels were made with 70 % gel coat and 30 % fiberglass fibers, this gel coat was very brittle and was common to see entire C1 bodies with spider cracks all over, in the 60's the formula changed to 60% gel coat and 40 % fiberglass fibers...cracking was evident around the corners of the hood and the corners of the headlamp doors... in the 70's the gel coat was 50% gel and 50% fiberglass fibers , all under pressure... the C3 bodies had plenty of flex and cracking became much less of an issue... In a gel coated car, the gel coat went completely through the body panel, these panels were not what is referred too as Hand layup... they were made using a pressure layup process.

Thanks all
I am putting on a C5R body kit, from c5west.com. The fiberglass and fitment are really bad so I have to add in some area and fill in some areas. I have sanded through gel coat in some spots and was wondering if I needed to gelcoat it again. Or just smooth it down and paint it.

thanks evil twin
I am hoping to have it done shortly, this will make it even better. I am mixing a C5R kit with a tiger shark rear fascia. Other than extreme poor workmanship from C5west it is turning out to look really different.
Thanks again

Who's painting the car? What brand of paint are they/you using? Most lines have a quality epoxy primer that flows very well and sands easily. I used PPG on the 74 and lightly scuffed the epoxy primer and then applied 2 coats of K36. I block sanded the K36 with 800 grit and then painted the base coat clear coat.

Sounds good
sounds like your 74 turned out great. I haven't taken any pictures of the C5, it looks ruff and wide now, but I will soon bedone. The car M Yellow with black top, so I will go back with that color. I don't know who makes the M Yellow.
