Depends on your riding style. If you're not likely to be putting them to the test regularly it would hold up I think.
I beat ours to death when we play in the rocks so I prefer spray paint. Just mask around them for quick touch ups and pull them a couple times a year and clean them up right for a fresh coat.

 

I would just spry paint them.
Rust-oleum holds up well and easy to touch up.

 

On my jeep, that type of stuff gets duplicolor spray on bedliner in an aerosol can. Holds up well, and is easily touched up.

And for larger projects, I think I like raptor liner. Sprays nicely, I’ve only got 2 years on it so not so sure about it yet.

 

The coating will scrape right off on a tree. But nothing is easier to touch up than spray on bedliner.

You can also use the spray can of underbody coating. It’s pretty much the same thing, just a little more rubbery.

 

Why stop there? I know a semi-local guy that Rhino Lined his whole dang RZR! He does it for a local Toyota dealership, so why not. Its a little beat up, but I kinda love how it looks.

 

I would ditch those expanding mounts and get some from Houser Racing. I lost one (found it), and tore another off half way at Windrock Park. After I switched, no more problems.
