When I removed my running boards I noticed that they had worn the paint down to the metal. I need to get that fixed once the weather turns better to help keep it from rusting in those areas. Has anyone had any luck with that paint repair kit from Walmart (has a bunch of items in a little box, if you know what I'm talking about). How should I appoarch this and what recommendations could you guys give me on to fix it. Should I just sand/scuff up those areas, apply some primer and then some paint or what?
