I’ll be heading to the salt with my Bro @hotdamn this year and wondered if any one had any recommendations for a pre treatment to spray the underside down. I’ll be covering the bottom of the floor on my 39 with spray on bed liner and have been looking at things that could be done right before we make the trek. I’was looking at Fluid Film and Wool Wax as it doesn’t appear to be permanent but a yearly application. Or would we be better off just spraying everything down with a couple cans of Gibbs? Any recommendations?
