Can anyone recommend a good/great rubberized paint.

I need to make a small skid as well as makeshift ramps to move the small engine equipment off the truck during seasonal changes..

I'm just going with 2x8 KD wood. No PT due to weight.

Besides, I want/plan to paint it with some rubberized coating so it's less slippery if it's raining or the wheels are wet.

Suggestions, thoughts.

Otherwise, I may just get cheap and buy concrete paint and throw some sandust in there...
