RE: thinning epoxy
The Marine grade epoxies are much higher grade than the 30 minute epoxy for coating and fiberglass fabrication. I just picked up more planes at a close out sale and my epoxy mix will take care of those and the other planes I have waiting to be built. If you didn't know about the marine grade epoxy you would probably spend alot of cash on 30 minute epoxy and get a infearior coat job. I want to get into making parts like a warbird fuse or cowell. A sailplane body would be nice too.
