the raging debate of marine plywood / fiberglassing / etc

what i really want to do is have plywood and then a
paint with sand in it to give a grip to the feet when walking.
Don't use sand (silica). It will be coming loose continuously and ruining
all sorts of mechanical things and surfaces due to its hardness.
Use pumice grit. Provides a tread, but doesn't spoil mechanisms if it gets
into a machine.
