Hi all, i have just made my 1st tool using woven glass. The tool has come out with lots of voids in it and its almost too poor to fill and sand. I bought easy composites epoxy tooling gelcoat. After applying the gelcoat i used an LY epoxy resin and woven glass. I really arent sure why its come out as bad as it has. I sanded my part down with wet and dry to start with then applied several layers of meguiars wax whilst also rubbing off. I then applied a coat of easy composites pva release. Then i applied the tooling gel coat with a brush........ i just let the gel coat get to a tack before applying my epoxy resin and woven glass. Should i have applied the gel coat and let it go hard before doing anything else or should i have also applied some chop strand mat after i applied the tooling gel coat and then let the whole thing go hard? Thanks in advance
