If I dont post cure the mould, how fast I can start making parts from the mould? If I release the mould from the plug, Am I ready to use the mould in next day? or will there be a styrene pockets or something? So basically I am asking how long it takes to have the mould ready for use.

Not that I recommend that, no doubt they wouldn't have a very long life, I just did it to get out of a bind with our race car. I dont use Unimould either, but there won't be a great difference between that and any other quality vinyl ester tooling system. Basically yes, you can put them to use straight away.

Next time i must use 1.5% ratio of hardener. First gelcoat layer did had some clumps now. I hope they will not affect in final mould surface quality. Never had clumps before, so no idea. It started to make clumps under 10minutes.
