I just purchased a new 07 chevy avalanche in dark gray met.(graystone). It has never been waxed. I want the best wax, sealer for the best wet look and durability. I will also be doing this by hand. It will not matter how many coats. I want something that will get better with the amount of coats used. Since I am a newby here. Please no abreviations as I probably would not understand. Also I need to know were to purchase these items.
