I know that much has been said about Collinite #845 Insolator wax but I just wanted to mention that every year I either buy into some other new wax, car polish or sealant from either some advertising or someone recommending something new to me. This year I decided I'm not going to buy any new product and went to my car finish product shelf full of half used stuff and decided I would try my 5 year old bottle of Collinite #845. All I can say is I really did not need to try anything new every year the "845" really works great and I think I'm just going to stick with it from now on it goes on easy comes off easy shines good enough and last longer then most other stuff I have tried.
