Line-x
Next winter I plan to have my frame sprayed with “LINE-X” truck bed liner, the guy said that he will charge the same as he does for a tailgate, which is roughly $40 Canadian. I think it will look sharp and turn out really tough, and not wear around my boots to fast. The line x spray can be put on with or with out the grip pebbles, I personally want the pebbles sprayed on, but they will likely make it harder to clean.
Just an idea for you, as the sanding supplies, thinner, and paint will probably cost $20 alone. And then wear off the first ride from your boots like mine did.
