Use chopped fiber, it will help get in the corners. Also sounds like you
mixed a little hot. Slow setup would help you too. Also use way more gel
coat, and wax the piss out of your part. Tooling gel is what I use when
making molds.

+Rodney's w123 I prefer the chopped fiber mats. They're stuff until you wet them with resin, the acetate in th resin eats the bonding agent used to make it a mat. Also you'll have better luck making a thicker first layer. the thicker the resin is the better it sets up, and less likely for it to seperate between layers of glass. Since you're overlaying without bagging keep a bristle paint brush on hand to poke out any air bubles, and even those aren't a huge deal since this is just a mold. I prefer a 1" brush.Are you anchoring the cover in any way before your trying to mold it?

You are exactly right on all of your points. I made a second one with chopped mat a few days later and it turned out better but my (tooling) gel coat layer was still way too thin. Being the novice that I am I think I just need a little more practice :)
