No gravity tricks. The epoxy is West Systems six-10. Comes out of a tube through a mixing nozzle, pre thickened, and it stays in place even on overhead surfaces.
There is one layer of fiberglass tape on the outside seams. It will get four or five coats of interprotect epoxy barrier coat before final paint. The barrier coat goes on with a roller, can be recounted in six hours and requires no sanding between coats.
Final prep will be hand sanding with 180 grit on a long board. Wash it down with a mild solution of ammonia and water and then paint.
The seam fiberglass is reinforcement more than abrasion resistance.
