The rough bodywork on the rear 2/3's of the bedside if done and in Slick Sand, ready to block flat. The front corner was giving me fits (bottom edge was folded inward under the wrap around corner) but I worked out most of that this morning. I found a sealer to use on the large gaps under the bed floor- Fusor 121 Flexible Foam. It expands 10X the size of what's dispensed and cures with a waterproof shell around it. It is open cell inside though, which I found out once I started trimming the excess back... Not crazy about that but it's too late to change it. I can shoot undercoating on it to seal it back up underneath, and the topside will have Line-X bedliner over it so it should be fine.
The gap underneath, 3/8" tall.
I'll run a bead of regular seam sealer over this since the foam will support it.
After applying the Fusor foam... it makes a mess!
