I have been using der shiney stuff and der real stuff on and off for about 1.5 years, only by hand, and it is absolutely wonderful. It is my go to polish/ cleaner/ protector for by hand applications. Now ive switched to pc and 1z products, but I will do a review of Der shiney stuff and der real stuff by pc when i get some time to kill, unless someone else has tried it? It has done some great things for minor swirls and ease of use. I know its been brought up before but no one seems to say much about it? The clay is supposed to be good? Just wondering what your thoughts are on it? Im thinking it could be a great "polish" to use between a full pc detail? I dont know how well it protects but it sure is the easiest product to use so far. NXT being a close second.
