I use their Jetseal and Jetseal Matte, V series polishes, and XXX (freebie) & Luminous wax. I like all but the Jetseal Matte, it has a tendency to leave swirl mark residue on my vinyl hood, it is their suggested product for it.
Are they better than any other quality care product? Dunno. Other than Einszett this the only other "premium" product line I have used. They have decent holiday sales so you can get a premium product for a good price.
The Jetseal seems to be a good sealant, pretty quick to apply, and buff off. Which is nice considering how much damn surface area these trucks have. I get about a year out of it before I need to clean and reapply. I have waxed on top of it a couple of times when I haven't had anything better to do.
