In 2011 I was introduced to the Ultima line but Corey, Jim (Dr Oldz) and a few other people. The entire line is very high quality, and I use them on almost every detail. Some of the products that totally blow me away from Ultima are:
UPGP - This is the easiest LSP to use. I'm a carnuba guy, but this product makes even me fall in love. It gives a super glossy candy shell look, but at the same time adds tons of depth to the paint, especially when you layer it.
UTTG - This product is easily the best trim product on the market, for maintained trim. It goes on super thin, a bottle will last damn near forever, it looks amazing, and it lasts for the better part of the year on trim!
Ultima also offers other great products like there Waterless Wash, Car Shampoo, Interior Gel Shampoo, Interior Guard, and their clay block system. All are awesome products that I would not be without. Overall I would say the entire Ultima line blew me away in 2011.
