One bottle of Super Gloss and I was sold. It's not a wax, it's a polish. It goes on easily and comes off easier and leaves a great shine
Grandpa Bosch’s Super Gloss is the Bomb! I have several motorcycles and they all look fantastic after applying the product. The surface is like glass!
I tell everyone about how good the stuff works! Use me as a reference!
