Most of the box is 3/4 MDF. The top & front are Fiberglass. I reall have no idea what I am doing, just trying to follow guides from this site. I made the wood part to fit in the trunk nice & tight. I used liquid nails in every joint for a good bond/seal & coarse wood screws. Of course I siliconed every wood inseam as well.
Any thoughts/ideas are appreciated. So far so good. I have resin'd the fleece & that turned out well. I have also done 2 layers of glass that I don't have pics of yet.
One thing I have to point out is that I went all the way down the sides & back of the MDF with resin then a thin layer of glass. I plan on bondo'ing these for paint as well. The only part that won't be painted is the bottom.
The frame. Lot's of angles. Hopeful that won't hurt performance:
Then I suspended the rings:
