An old hand once told me to use crushed graded walnut shells for non-skid. The stuff is sold for 'sand' blasting soft metals. Once they are sprinkled on the wet paint and it dries, another coat covers them up so they don't look like - well - spilled nut shells.
They work about the same as sand. The advantage is that when you want to renew, they sand right off, unlike real sand.
