I kinda always wanted to try his IUDJ, but I didn`t like the price. Well he released a new line, and the new version of IUDJ is THREE HUNDRED BUCKS for a gallon. From the best I can tell this is basically like most rinseless products. Now I`m not talking how well it works, I`ve never used it so I don`t know. I mean it`s purpose of use. He just really pushes the fact you can use as a clay lube, a detail spray and some other things. Which I can do with the Wolfgang UBER Waterless Wash I have. I`m not trying to put him down, I know people are very opinionated on him as a person and how they feel about his products. As someone who owned plenty of Polish Angel stuff, I was still wowed when I saw the price of the gallon. I think I need to stop detailing and learn how to make detailing products lol.
