I was needing an idea of how much gelcoat to order. I have a 97 triton tr-21 I am preparing to shoot. Going to do entire boat solid color except for the triton stripe. I will do it black base with flake clear over top. So I will need white, neutral and clear gel. Can someone get me in the ballpark? I will need some extra cause I plan on shooting a go cart body before the boat. I wont mind having a quart or half gallon or so of each left over. I just don't want to order way to much.

Thanks for help,
