Making aluminum non-slip
I worked on a custom built mud racer years ago. The body and floor boards were unpainted 5052 aluminum for corrosion resistance. Our driver complained about how slippery the floor was. The answer we came up with was 36 grit aluminum oxide sanding disk on a DA air sander. The aluminum oxide did not leave any trace metals to discolor the finish and the circular dual action pattern made an excellent non-slip. No more driver complaints and easy to clean.
