We drill the a ,b pillers high and apply inside then plug. Also inner fenders , bedside behind lights, complete underside , inside frame rails , drill back side of rockers and then plug. Inside doors from upper frame down, jambs, hinges , mirror frame, mounts , under hood all seams, roof , the rack , behind grill, light pockets, rad support in and out. All chrome, front and back of bumpers which we paint with two part when new. The whole truck!
Every vehicle that I have and is driven in winter gets this.
I've seen 5yearold Duramax, Rams, Fords, with rotten cab corners and beds. Up here the roads are harsh , covered white with rock salt and salt brine from late October till mid April. Nothing lasts, not even a Toyota lol
