Hi there,
New here and I'm trying to get my mold technique down but failed last night.
Using epoxy gel coat and used AFH release agent x 3 and polished...
This is the second mold I had made of the same part however on my second attempt when releasing the mold ended up with the mold breaking into many pieces.

Any ideas?
Used gel coat for two passes then 2 sheets FG matting for the strength however not sure what I've done wrong.

Was the mold not rigid enough or not enough release agent?

Many thanks in advance.
Jay

Getting there with the molds but that fender has some weird angles etc so jumped in the deep end. Done side panels with good results. Just got to master vacuum bagging now but going to do it later this year so will report back. 
If anyone has the same panels can help you with parts for minimal cost.
