Endless sanding

Last week I stuck on some Epoxy Filler to fill in some gaps and low spots. I spent a lot of time today sanding it smooth, thinking all the while that I had put on too much. At the of the day it turned out I still had some low spots. The day ended the same as last time, a coat of POR-15 on the fiberglass patches and Epoxy Filler on the low spots. Obviously more sanding next week.

The star tool of the day was my long block sander. Loaded with #80 paper it cut through the epoxy rather well. Slow, perhaps, because the stuff is so hard, but that makes it harder to make a mistake.

The challenge is to create a continuous curve between successive high spots. In the places I've been working those high spots are along the edges of flat sheet metal patches. Even using a block sander it is possible to create a wonderfully smooth surface between those high spots and removing too much in the middle to produce a smooth, continuous curve.
