First you gave to use a degreaser (I used 3m) then you have to scratch it up pretty good with a scotch brite pad( I started at 120 grit and went 100 then 80) then degrease one more time. Clean with a microfiber towel. I used bedliner on mine but you could use any automotive paint, hope this helps! Post pics if you do it!
