I mean people on here say do 8 - 12 layers, I mean I did a fiberglass box with 3 layers and that was with some weak 8" though.

4 layers will be strong enough to pull the mold out. Just reinforce it in the areas that are flexing under pressure.

depends on how many curvs you have. the first rule of fiberglass is that it is wicked stong in curves, but weak in flat areas. i would think at least 3-4 more layers will be needed tho. better to do it right the first time than re-doing it later. ~Ryan

Yeah a good test is once it is completely cured push it with your thumb, if it flexes reinforce it. If not you're good to go.
