Review: Works exactly as advertised - Don’t usually write reviews but was very impressed with this, does exactly as advertised. I purchased an 8 year old car which had been polished by a garage, but wanted to strip all polish and wax prior to re-waxing. I used a fairly high concentration in a foam gun, and again a high concentration in the bucket. When finished no beading or sheeting on the vehicle at all so clearly has stripped away all the old polish. Great product did exactly as advertised!
