I have used a lot of car care products over the years, mostly Meguiar's and 3M, but in the last couple of years I have switched almost exclusively to a local Colorado company called Detailers Paradise.
Detailers Paradise: Premium Car Care Products, Auto Detailing
Their Epic wax (actually a synthetic sealant) is very easy to apply, has great gloss, and lasts about 6 months on my daily drivers. They also have a new wax called Banana Gloss, which I haven't tried yet but am very excited to try. I use their quick detailer spray all the time, which is better than anything I've used, including Griot's.
OK, so their products work, but back to why I am so impressed with them:
1) The company is owned by a couple of Alfa owners, who are also some of the nicest people you will ever meet and will bend over backwards to help people with their car care issues!
2) Believe it or not, their waxes, polishes, detailing spray, etc. are all made in the USA.
Last year they made up a special detailing kit for us at Centerline (with a trick custom bag), which is still available, but for the full range of products you can just go directly to their site.
