I just repainted mine for the 2nd time. They blister/rust around the obrounds punched into the surface. Except for the anti skid appliques, I sanded them down with a air disc and about a 40 grit, wiped down with alcohol and shot with a rustoleum product that turns rust to primer and then a finish coat of rustoleum satin black. Good enough until next time!
