I'm sure some of these have been mentioned. Collinite 476, 845, Polish Angel Master Sealant, Soft 99 Fusso Coat (Epic water behavior, durability and starting to get cheaper in the states) Prima Epic ( I have personally had 7 months with 2 coats before it started to fail with proper maintenance and detailer spray toppers. I'm sure there is more.
It all depends what you are looking for there are always trade offs but they are becoming less and less with the introduction of Si02, Ti02 into traditional wax and sealant formats. If you wants tons of Gloss and Durability and can handle the one time cost of admission including upkeep products, the stringent guidelines for install get a coating. If you want easy do it anywhere durability no special tools needed get a traditional sealant or a heavy hitter wax like 476. If you want something with the look of a great wax or sealant but 1/2 or slightly less durability of a coating grab a hybrid wax or a coating sealant. They are expensive up front but you will be able to use them longer because the shelf life is longer then a coating. You can look into TAC Systems Moonlight, Jays Wax Ceramic, Angel Wax Enigma, Fireball Fusion, Kamikaze Infinity, In2Detailing Ceramic, Wax Planet: Oblivion and Shield of Dreams V2, WaxAddict: Quartz, Kudos and Vortex, Edition 21, Power Maxed Tsunami. Some of them can be had in panel pots which allows you for a test drive ( I don't know of any coating to be had for a test drive.) yes some panel pots are expensive but some can do a small sedan twice. Many of these will be hard to find in the states but shipping from some of the UK companies is not always expensive or they flat rate you a high price. I think Wax Planet is reasonable on shippiing. You would have to send emails and get prices to make sure there are no hidden export fees.
