Fiberglass parts will only be a problem if they are released from moulds to early,I have seen "soft" parts taken off a mould that have gone out of shape.
Parts like bonnets,spoilers and the like don't normal have an issue as they are laminated together in sections to make the final part.
You could post-cure the parts in a warm enviroment if you aren;t sure ,that will bring any small impefections to the surface also.
Besides the poor fit of parts there is the issue of how they are made and the materials used,I won't go in to that because there are so many wrong ways to do it,good luck.
