I've transitioned away from paste / liquid waxes kicking and screaming, but its all for the better. Something magical happened to TurtleWax where they struck gold with their recent line up. They did such a good job on Seal and Shine that the the other two products are not all that much more durable, but have other improvements.
TurtleWax Ice Seal N Shine $11
-Cheap, duarable, good shine, and blows entry level professional products out of the water.
TurtleWax Hybrid Solutions Ceramic Spray Wax $13
-The best bang for the buck and a notch better than seal n shine due to the increase gloss that occurs after the 24hr cure.
TurtleWax Hybrid Solutions Pro Graphene Flex Wax $23.99
-Easiest to use, provides the best gloss, but the price removes any reason to use it. The slight increase in durability is not worth the added cost. Under $20 it would have been a bargain.
