Top picture is repaired door base support.
Middle picture is frame painted and ready.
Bottom picture is wood floor with block between wall and new wood with second block propping floor up. This is so I could put bead of construction adhesive on trailer frame to seal out water and access the wall to put fiberglass resin on at the same time.
Construction adhesive has a longer pot life than the fiberglass resin, I had everything ready to go. Drill for pilot screw holes, Drill to drive the screws into the frame, weights to hold the floor down.
If I had it to do again I would put the construction adhesive on the frame before adding the catalyst to the resin. Had to work pretty fast to get it all done before the resin started to set up.
