Nothing wrong with AG products at all. Not sure that the Super Resin Polish no longer contains abraisives. Only heard that the new formula is even better than the old because it doesn't "dust" as much. I've used it and it's brilliant.
Also use AGs HD Wax which is superb. Very easy to use too (if you use it sparingly, as you should).
Have tried stuff from Meguires, Poorboys, Autobrite and Angelwax - which were all very good. But not that much noticeable from the AG stuff. If at all.
Plus, the AG stuff is easy to get (as is Meguires) from your local Halfords - who often have a "Buy 2 get 1 free" offer on. So I wouldn't write-off AutoGlym just yet . . .
Oh, and AutoGlym's Aqua Wax is an absolute must-have in my humble opinion.
