I am wanting to bedline my Mopar bumpers and rock rails why I have them off. They are basically brand new and were only on my last Jeep for about a month and I am already noticing some rust at the welds. I can take all of it to Rhino and they said $350.00 to 400.00 or I can go buy some spray can liner and do it myself. I just am not sure how the can liner would work on a powder coat. What do you all think?
