Re: Refinishing Speaker CabsI've found that the Line-X style coatings tend to hold dirt well, and are difficult to get really clean. The finish does last much longer than paint though. If you are looking for the corporate shine, I would paint and keep painting on a regular basis. If you just want it black and looking decent without having to do regular touch-ups, then the truck bed liner is the way to go.
