Just got my new truck last week but it's pretty gross already. It lightly snowed so there's some salt residue I'm sure.
I keep reading that there's a wax coating on the underside, and you shouldn't pressure spray since it damages it. The salt sitting there scares me though.
Also I've read that washing it may remove the coating the factory puts on the paint? Would I have to rewax?
I'm planning on a ONR wash after a touchless wash for the underside.
