CARPRO PolyShave Decon Block - Car Detailing Clay Decontamination Faster Than Clay Bar, Cleaning & Release of Paint Contaminants and Glass - Increase Wax and Sealant Bond - (1 Pack)

Works great.

I can't believe I fooled myself into buying this rip off product. Although the product presentation is nice in its plastic box and label, the product itself is just foam on one end (to save precious clay lube) and a rubberized polymer on the other end. I think it was just rubber.I used this on a session to get rid of Tar from my paint. It was worthless. I spent 4 hours due to the ridiculous inefficiency of this product. If you apply slightly more pressure on a point, the rubber, due to friction would melt onto the car paint. That is frustrating to get rid off. The product is of NO help in the Clay Barring process. Your nails would be a much better alternative.Want to save yourself precious time, and efficiency? Buy some MOTHERS Clay.If you want to buy your teething puppy an expensive chew toy, buy this. I see no other positive applications for this junk. Not Pleased.
