Today I spent on the bottom half of the bottom panel. First, I remade my sac sheets and covered them in plastic to place my bottom panels on. (look familiar?)
Then , I glued the key joint of the bottom panel together with the peanut butter like epoxy compound. And lastly, I glued the butt joints of the side pieces for extra width.

After epoxying the joints I mixed up a relatively small batch of clear epoxy and spread it over the bottom in order to provide a tack coat for the Kevlar to be applied next. Kevlar floats in epoxy, unlike fiberglass due to its density, and therefore needs to be glued down before it can be wet out. After the tack caot had an hour to "tack" up, I rolled out the Kevlar and smoothed it out on the sticky epoxy. An hour later I mixed up more clear epoxy and wet out the Kevlar. Next I rolled out fiberglass onto the wet out Kevlar and then wet out the glass with more epoxy. Lastly I placed plastic covered boards onto the joints and heavily weighted them for drying.
