When I finally get around to building my 'dream machine' AD pickup, i'm going to paint the running boards black.. and probably going to coat them with that chunky rubberized stuff they use for pickup bed spray in liner.
AD running boards do two things: They get slicker than snot on a doorknob when they're wet, and they tend to collect pools of water that can lead to premature rot.
Coating the running boards with that spray in liner stuff kills three birds with one stone. It looks good, it is an extra level of protection from 'pooled water rot syndrome' and it makes them a lot less slick when they're wet.
