I skinned the inside of my boat w/ alum. looked at many options, but finally used a beige water base exterior from lowes and added the non-slip grit additive. It did take a while to dry, but I painted it in febuary so thats probably why. On the sides I used a beige oil base auto paint with no grit. It looks great and did not cost more than $40.00 for everything....hope this helps
