I just done this a week ago!!
I got in with a wire attachment on my grinder and every flat surface pretty much wiped till no rust, or every big loose chunk was off.
I then used a regular primer on the bare metal, or metal with some rust etc.....
And on top of that added bedliner black, both...
What year were they off of originally? Can you send me a PM? I don’t think mine are coming through or something. I’m very interested and intend to purchase if everything is alright.
