I will be possibly building a fiberglass box in the next few weeks for my Tempest, around 4cf and i'm trying to figure up the amount of resin, and matting that it will take me to build the enclosure. I was going to make a mold of the rear cargo area and then wrap a fleece covering over the entire top of the box, (added speaker mounting ring as well) and all in all i would just like a good figure of how much matting, resin and hardener i will possibly need to complete my goal. So any of you fiberglassers out there care to help me out. Also a good idea of the total amount everything should or could possibly cost would be a great help as well. I've looked at different stores around my area for materials but havn't found many at all. All so what are some of the best brands and all to use.
