I think this was double polished in October? Just washed a section and unbelievably it still just about beads and feels that little bit greasy. After decades of Brand Loyalty to Autoglyms SRP and the ultra Gloss. 2 coats of the former and one of the later looks good for 3 - 4 days and is basically all gone by the second week. Whereas Collonite 476S looked great for 3 months and looks like its still protecting after 5 or 6 months. In perspective its incredible value for money, and less effort ( AG would have needed 6 sessions) In summary saved me a fortune and did a much better job! It was clayed before the Collonite. I am not an expert like Carl in any way, but for me at my evel this stuff is awesome. It also wasnt difficult to apply , and a no white dust.
