Hi,

I made my mould using the unimold system starting with black tooling gel coat, after polishing the mould I applied 5 coats of easy-lease.

I thought I should test a small amount of the gel coat I intend to use on the mould first (e c fibreglass polyester) info here

I'm glad i did the test because it won't release at all. I also mixed up a small amount of Easy composites general laminating polyester resin to test on the mould,
this released fine!

is there any reason why the EC Fibreglass polyester gel coat wouldn't work?

OK Cool, So maybe I should give the mould another 6 or more applications of easy lease, The only other factor I can think of is that the catalyst ratio was off? it's hard to weigh accurately when mixing such a small amount!
