sorry boys and girls....this project is over
if you ever make a mold from ABS with polyester resin you better use pva after the coats of wax. if not your part will be eaten by the gelcoat and stick to the mold to no end.
thats what ended up happening to my lower hull that is now junk. the only reason the other parts came out ok was i used 9 coats of wax with 3 coats of pva. this will never happen again after what this cost me.
the mold may be saved if i can get the other parts out. the mold will need extensive work to be ready for parts.
