I used some gorilla glue 2 part epoxy to add texture to mine. I used the transparent variant to sort of bed a flat surface for an arca rail, and the black stuff from a tube on the grip area. The black stuff finished up more rubbery, a better texture imo. Looks like the black epoxy pic is a little blurry, but you should get the idea. The clear stuff is smoother, harder. I scuffed you the plastic stock to get it some teeth to adhere to. Has worked out well.
