I have used the Autoglym products since May--and have been very pleased with the results.
Both products are very easy to use--I initally applied the Super Resin Polish and followed it up with the Extra Gloss Protection. I used microfiber towels to buff them both off--it was very easy. Applied a second layer of the Extra Gloss Protection one week later (you don't have to, though).
Products leave a very nice finish on the paint. Two months later, and it looks like it was applied yesterday--and as crazy as it sounds, actually looks a bit glossier (to my eyes anyway).
One thing I wish I had tried, was letting them cure longer re: Ron K's posts regarding polymer sealants. Still I'm very pleased with the results--and I have used Blitz, Klasse, P21S, and Meguiars products, among others, so I'm a bit of a fussbudgit.
Also have used the Autoglym car wash and Glass Polish. The Glass Polish works nicely removing various contaminants from the windshield--the car wash is a little weird--not much sudsing action--reminds me of the Sonax Car Wash I used to use. Seems to work okay though--I guess suds aren't that important.
Recommended by a couple of car makers in Britain according to the labels (including Jaguar, if I rememeber correctly)--I like when I see manufacturers recommending a product to be used on their vehicles.
