ok so i set about making my first mould. as some of you know ive had to use polyester resin as i was misinformed before i purchased my supplies. anyway ive got a few questions to go with the pics ive uploaded. why did the pva bead off? i assume its not compatible with the wax. i cleaned it from the part and just waxed it again as i didnt want these beads in the mould.
can i use the tooling gelcoat again with carbon fibre or chopped strand to reinforce the mould? or can i use epoxy laminating resin over the cured polyester to reinforce it?
thanks
