Repainting vinyl-coated fence posts
Vinyl-clad chain-link fence keeps its appearance for a long time. But the vinyl can get scuffed and worn where the gate latch locks onto the post. The repair is a little tricky because you're trying to paint over vinyl and metal. If you use a spray paint formulated for metal, it won't bond well to the vinyl. Instead, coat the damaged area with spray paint specifically designed for plastic (Krylon Fusion is one brand).
Start by cleaning the damaged area and beyond with a household spray cleaner. Then rough up the surface (Photo 1). Finish the repair with special plastic paint (Photo 2). Let the repair dry at least 24 hours before operating the gate latch mechanism.
