Query: Deep Long Lasting Gloss

I have been using this product for years on my vehicles with great results. The wax is long lasting, durable and provides a nice deep, wet looking gloss. It performs fantastically on fiberglass too. My 2000 Red Corvette get's treated with only the best and I rate Gliptone up there with the best of them!
