I have a 6-piece mould made from the Unimould system. There are a few minor imperfections along the parting lines that needs to be adressed before using the mould.

Yes, I'll envelope bag the whole thing. My issue is these small broken off pieces along the mould parting lines...but I guess I'll use some Unimould tooling gelcoat to fix these. What exactly is the kind of "wax" to be mixed into the gelcoat, and at which rate?
