I like Duragloss AquaWax best. However, lately I have been using something that I'm not sure what category it falls under - "Slick Mist Spray Wax", by Lucas. It is called a wax but it does not contain wax (the same is true of AquaWax). Instead, Slick Mist is a polymer product which makes me think it is a sealant (again, like AquaWax) but nowhere in the literature does it say it is a spray sealant. The description is somewhat vague even at the Lucas website where Slick Mist is simply given a generic label as "a polymer paint gloss intensifier". Slick Mist is also similar to AquaWax in that it can be used as a "topper" on a dry car or as a drying aid after your rinse. In fact, if it were not for the distinctive smell I would swear Slick Mist was AquaWax. It acts the same and looks the same.
Although I may not know exactly what Slick Mist is or is suppose to be, I do know it works to give excellent gloss and slickness and a bit of protection to your paint as well. It is very versatile in that it can be used in different ways, it has some cleaning ability so it can also act as a QD, and it smells great (think a bubble gum factory). As a bonus, Slick Mist is bargain priced (even a little cheaper than AquaWax which is an excellent value itself) and available locally at all auto supply stores and even places like WalMart. I may not know what Slick Mist is but it is a winner for sure!
