They're all scraped up and whatnot so I'm gunna take them off, sand em' then I was wondering what I should spray on there to make them extremely durable.

Something like rhinoliner? idk I've never done this.

What do y'all recommend?

 

That roll-on bedliner that Stryker put on his floor, or I think JakeWI used on his rockers (Which I love BTW) looks like a good deal...

 

Try to check RustOleum Spray Paints for your bumper....
My wheeling buddy have used it to his rear bumper and it looks good...

 

I used Duplicolor spray bedliner. Just sand the crap out of them first, wipe them down with acetone and spray.

 

Is that what you have on the 1/4's too?

 

I forgot to mention that I could have them powder coated for dirt cheap. Should I have this done?

 

id get them powder coated if its cheap. but i used the duplicolor spray on liner on my rear bumper and it has worked pretty good

 

Yep my quarters and rockers are done with it too

 

I use the cheapest satin black spray paint i can find. its going to get scratched up anyways and that way its easy and cheap to recoat.

 

how long did has the dupli-color spray held up xjjeepthing

 

I wouldn't powdercoat it because if it get chipped on a rock or whatever, then you have a scratch that will rust. And you wouldn't be able to quick fix it like paint.
You could try a Hammerite paint job..??

 

Its been there over a year now. No problems. You just have prep it correctly.

 

the rustoleum hammered looks good.

 

I am surprised, with all the answers given, and NO-ONE mentioned the easiest and CHEAPEST.
