So I live in the salt belt and have spent most of my life fighting rust. For the last 10 years I have been using Fluid Film on my daily drivers with good results. Unfortunately in the last couple of years they have been coating the roads with battery acid or something worse and I can see I'm starting to loose the battle on the old 2002 F150. The new acid has something to do with beet juice and they pave the roads with it if they think it might snow. It fails after a few minutes and turns the roads into a sheet of ice. But you know it's the government and intelligence is not their strong suit. I spent 4 hours today swimming in Fluid Film under the old truck in preparation of 4 inches of snow tomorrow but think I might need to up my game a bit if possible. The weekend cable auto shows are pushing, with compensation I'm sure, NH oil undercoating. So has anybody used it?
