Easy and very cost affective.
I was changing my running boards and was shocked by the condition of my rocker panels, and the cab corners. I brought my 2012 F 150 to a few body shops but they never called back with the quote. I went back to inquire, and was told that nobody really does rocker panels anymore. So, I searched for another option. I found OAM, and watched the videos. Seemed like my best option. I purchased the textured option. Being my truck is Tuxedo Black, and my new running boards are all black. The videos made everything easy to do. I watched them 3 times so, when I installed them, it was like I have done this before. Lucky for me the rust did not permeate to the doors.
