The time has come to re-paint my rock sliders. The rust oleum gloss paint has lasted a few years and I did a pretty quick (no primer) paint job to them the night before a trip so I can't complain. This time around I would like to strip and primer them so they hold up better. What do people recommend for prep/primer/paint? Spray paint or other. I've never bene great at the paint side of things. Since these are sliders I know I'll need to re-paint them on occasion so I certainly want to use something that can be touched up down the road.
