I really appreciate your commens Darrin... It's nice to chat with people about "shop talk" on these things.

I have been trying to get away from PVA for awhile. Bought some wax to try on the Tsunami stab. That mold has been well waxed, so the part should pop out ok. However, the wax that I used did not like the primer. I had to mist it on or it would get dots where the paint pulled away from it (not sure what the term is), but basically it looked incompatible. We'll see how it goes when I pop it out of the mold.

Believe it or not, I only used the 4oz on the inside (I think it was 4, could be 3) because I ran out of 2oz. My layup was:

primer/2oz/balsa/4oz (plus carbon in some areas)

Do you think 1/32 would be too thin?

What do you use to close up the molds? what type of material?

What do you make your molds out of? I hear a lot about tooling resins.
