Flash, I have only read the first page. David Fermani, Scottwax has had OC on for over 4 years and still bead like day 1. If you need longer proof, Anthony Orosco can provide for you longer examples.
Now, anyone who thinks that Cquartz outlasts OC (OR any other LSP), needs some coating 101 lessons in a hurry. :dblthumb2:
OC is a ceramic clear coat. That is it. 22ple, Cquartz, EXO etc... while they are also called coatings like OC, they are not clear coats. They are sealants. But, very good ones. Only OC claims permanent protection. CQuartz claims 24 months.
On another note, about the other claim, that OC doesn't look as good as other coatings, is simply not true. If in doubt, any doubters are welcome to come along with me on any of my details. OC will provide a very deep wet looking finish. A thick look, which in fact makes sense, because you are adding actual clear to the finish.
If OC is applied/prepped properly, it will not come off the paint. UNLESS you have it compounded off.
