    Thanks lads,

    I mix up the MEKP and resin first , then add the talc. The talc is recent. As subculture mentioned I should try some of this silica or even an epoxy gel coat. Any other ideas?

      Another method i have seen used is to mix some polyester bodyfiller/putty with resin to thin it down a bit, and use that in place of gelcoat. Haven't tried this personally, I believe that bodyfiller is mainly talc and resin, but they probably stick some other stuff in as well to make it a bit lighter and more elastic- manufacturers don't tend to make public their blends.

        I would add, make sure your mixing well......Change cups was a tip I got from a demo by Smooth-On. the idea is the sides and areas around the cup surfaces may not get completely mixed even with the best intentions, but pouring the mixture to a new cup eliminates that. Test on small area first. A whole hull can add up in cost, but a bust of David Merriman would be small (or some other subject). I know these are common solutions and I am sure you know these things.....just going back to basics helps me.
        If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

          Is there anyway to cure the gooey spots like vacuum bag it; or is it done catalyzing?
          I read " I poured some of the hardener onto the brush and painted it onto the sticky soft spots and applied some heat from the pistol hair dryer. "
