Come on Goodmark!
Take your original if its just lightly pitted, get it sandblasted, then coated with rhino liner. I had my truck bed spray liner coated a few months back, and asked them if they i could throw in 2 battery trays with the deal. They said sure no problem. Just a battery tray, they might charge you $10-$20 and spray it when spraying somebodys truck bed.
