Pros: bad on paint and glass

Cons: great for vinyl and some plastics

Bottom Line: I am in the car detailing business. The shamwow is terrible on paint. Lots of streaks and not good on glass either. That said, the shamwow works great on vinyl tops, thresholds and certain plastics. Would give it a 100% rating for those applications but 0% for paint and glass. Therefore, 3 stars.  Permalink
