I just bought a 1973 Bronco and the PreRunner Front Bumper and Roll cage has rust on it. I want to refinish it myself without all the expense of having to powdercoat it or have someone else do it. What is the best way to prep? What type of paint should I use? What is the most durable and has the best look. I want it to look good and not like a half assed job. Thanks for the help in advance!!
