So I layed up another helicopter canopy, this time with frekote instead of pva. Came out beautiful, perfect gloss right out of the mold, but it took a little peice of the gel coat with it. It was a piece of the corner where it goes to the flange. About 10mm long, 2mm wide, not very big. Can I repair this? I used polyester tooling gel coat for finished mold surface. Should I just try to fill it in with the same stuff? It's pretty runny but I might be able to use some tape as a dam to hold it in place. Is this likely to work, or will I just lose it again? I suppose another option is to just fill in the corner with wax the next time I use it. Not a heavily used mold. Might do a few more canopies in it.
