I sprayed my tool box with self etching primer. Can be found at wal-mart for about 3 bucks a can. I took the red scotch-brite pads and scuffed up the whole tool box, then I cleaned it off with some soap and water. Spray etching primer per the instructions and spray the truck bed liner on over that. I used the rustoleum or whatever wal-mart has and it has held up supprisingly well. I have the running board style steps and eventually I will probably spray them the same way.

 

Yes, that was me. My method was to clean/degrease mine and scuff it down with a coarse Scotch Brite pad. After it was all prepped I degreased it one more time and sprayed it with three coats. Still looks fantastic and has some good grip.

You most definitely need to scuff it down as part of your prep. Primer isn't necessary but I'm sure it'll help. Most bedliners will adhere to almost anything so as long as the surface is clean you should be good to go.

 

Hey since I found ya or you found me, what kind of degreaser did you use? I have a bottle of Purple Power at home will that work? Also did you do just them metal or the plastic pieces also?

 

I used actual autobody wax and grease remover. I used Duplicolor wax and grease remover. You a lint-free cloth, soak it in the wax and grease remover and then wipe off the nerf bars. Then you take a dry lint-free cloth and wipe off the excess wax and grease remover before it has a chance to dry. Real quick stuff, and you'll even notice some dust and dirt that you would never have noticed before on the rags. Takes 2 minutes. Personally I did the entire nerf bars, front to back and from top to bottom. As I mentioned they were originally stainless steel but the previous owner painted them black with some cheap *** enamel so I used rockerguard. They still look great and they have even better grip than before. Overall it cost me about $30 for all the materials and it took me a little over 3 hours with curing time.
