I was a little skeptical, at first if this if this stuff really works. When I got my truck down it looked brand new underneath. Lot easier to clean, nothing sticking to it. Very impressive, been telling everyone about it. A must if you own a 4x4. Thanks again for making amazing products.

I like the Salt Shift much better than other undercarriage rust treatment as Salt Shift does not turn everything black. The frame and running gear looks new and it coats without changing the natural colors of the other components. Two thumbs up!

I’m 55 this year. Was a detailer before my mechanical apprenticeship in the early 90’s. In that time I can tell you of 3 products I would recommend because they work. A particular black RTV silicone. A particular injector cleaner in a bottle. And rust shield from salt shift. I just did the recommended 12 month reapplication and the results are amazing. I almost felt like it didn’t need the top up. Sensational.
