I got some rocker guards for my jeep last summer and thought i was doing a good job prepping them. I cleaned them with purple power,rinsed thoroughly, sanded them, then rinsed again. I used self-etching primer andused Krylon fusion olive green spray paint on top of the primer.
We have only seen 4 or 5 uses of road salt here over the winter,but the rockers are already showing some rust in several spots. I really laid the primer and paint to these things, so I'm surprised that they are rusting already.
Is there anything else I should have done that wouldn't cost too much and could've made the paint job last at least another couple of years before rusting?
