I am building a fairly large fiberglass box in the hatch of an eclipse and was wondering about how many layers do I need to put down before I can pop the mold? I am using masking tape so I really dont know how hard it will be to remove. Also how many overall layers of fiberglass do most people use to obtain the proper strength? And since my mold is going to be pretty big should I do half of it then pop it out, put it back in and then do the other half?
So far everything is going good I guess but any suggestions or info will be helpful.
