It had some minor rust and I used a wire brush to get most of it off. I also used a high pressure water spray to knock off the crud underneath and peel off loose paint. I then shot it with Rust Oleum red primer Professional Grade.
Painting: I picked up 10 cans of Hammered Black by Rust Oleum and used 6 in painting it. This did not include the inside of the tub as I am going to Line X it.
Tub: Got it Line X’d to match the tub of the Jeep. Its expensive, in fact way too expensive but worth it.
Time: <2 hours to prep included painting and removing or covering items not to be painted.
