Again, it's most likely slight shrinkage of the resin following initial cure
This will be more apparent if exposed to heat and a post-cure at elevated temperature is ideal. The parts will show signs of shrinkage after a post-cure, but doing the final flatting after that should give better long-term cosmetic results

Sounds like you're experiencing shrinkage of either the epoxy or polyester resin (not certain why you're using both in combination?) This would happen more readily if the parts are exposed to heat.....
