I found an old can of Collinite 915 in my cabinet tonight and decided to try it. I gave the Prius a quick hot water ONR wash and applied the Collinite 915 with a damp applicator pad, thus resulting in a very thin coat. The car had been clayed with a moderately aggressive clay 3 weeks ago and had a coat of DP Poli-Coat on it before this. After spending nearly 2 hours on the application and removal, I now understand why I have not used this product in a very long time. It is a major pain to remove! It is very difficult to remove this product from the paint (compared to DP Poli-coat) and I probably put a good amount of scratches into my paint in the process of doing so. This stuff is already supposed to be easier to use than 845. Has anyone else tried 915 before? The shine is fairly good, even at 1 am under florescent light, but it is hardly seems worth the trouble to use. Does anyone want to buy a can of 915?
