Just recently detailed a '07 Ford Ranger that was in dire need of a complete detail and paint correction. After a really good wash, I started to clay and realized after one front fender the paint was heavily contaminated. So I decided to break out the Sonax fallout cleaner and give it a try. I'm glad I decided to, that removed a lot of the heavy contamination on the paint. I first sprayed entire vehicle down then went back over it a second time along with a wash pad. Hosed all of the product off and then went back to claying. Definitely helped remove a lot of the contamination, the area I had first stopped on because contamination was so bad had cleared up a bunch. I'd recommend this to anyone doing a compete detail on a lightly or heavily contaminated vehicle. Makes removing contaminates easier and shortens your clay time by a few minutes. Edit: Just noticed I posted this in the wrong section.
