Ugly tramp frames

My tramp frames are looking kind of ugly and faded. Re-anodizing is kind of costly. Has anyone tried "Rhino Lining" on the frames? Being a textured material it would be more non slip, and not scalding hot on the butt like aluminum. I put the stuff on my truck bed and it is extremely durable and reasonably priced...

I'm no expert but I would think that Rhino lining is heavy stuff. Maybe something simple like paint would do the trick.
