I had a friend put in a spray on rhino type bed liner material. Worked great except he went with a dark color that made it real hot in the summer time!

...if you want to go cheap...25 or 30 shower strips work well...just be sure to clean the spots w/alcohol before stick'm down...cheers

call me we can take my boat.no problems. need to take the shine off!!

put a nice thick coat of paint with a roller and when its still wet throw a lot of sand on top of it to cover the whole area, you end up with a sandpaper like finish that isnt too rough but has good traction. i tried mixing it into the paint first but it gets lumpy clumpy and makes a mess so paint then add sand while wet.

pick a light grey color so its not that hot in the sun

Some great ideas here. More comments welcome. Thanks everyone.

they make a grippy paint that u paint cement steps with got some at a lumber yard how will it work on aluminum, dont know???? remember b4 painting its all about preparation for the paint to stick good!! good luck!! also a friend of mine bought a kit, its like rhino liner, and he did his boat with it! he said it dont come out as good as going to a pro, but hes satisified with it and much, much cheaper!! don't know where he got it??

Sherwin Williams sells a product called shark grip. It is a paint additive. I used it in a very wet area and it works great. We added it to two part epoxy paint.
