only way to fix it & make it look decent, is to buy metal rail caps, then you can have the over the rail spray done & it looks great
My Line-X guy said to remove the Rail Caps, spray the liner over the rail and then replace the railcaps, If you can't use the old ones, new ones are about $30.00 per side from Mopar. I want to put a Canopy on my box but I had a concern about movement of the factory rail cap on the rail, wearing away the paint. The idea was to remove the factory rail cap, spray the rail with Line-x, and then replace it, that way if the rail cap moves with the canopy on it, it can't wear away the paint because the rail is protected with the Line-X.
