Another issue with thick layers, is that the products are formulated to work in conjunction with air to dry. This allows the product to "set up" on the paint. A thick layer will take forever, if ever to dry. This leaves the wrong chemistry on the pain after wipe off, because we essentially wipe off wet product.

A thin layer can set up properly on the finish, especially essential for polymers that need time for crosslinking to occur. This will deliver maximum durability from the product.

I had a friend who used to use a half a bottle of Gold Class on his car when we were kids.. Recently we were tending to his truck. "Really, that's it??" Was the comment from him, when he saw how little product was going on the pad. It was hilarious! He said: "I always wondered why it was so hard to get off the car..."
