Autoglym

I have been using it for a couple of years and I love it.

Its the same chemical formula of the Autoglym Super Resin Polish but sold in professional line of products for a lot cheaper. $15/1L compared to $12/325mL. It functions somewhat like Klasse AIO in that it is a good cleaner and provides protection. I use the Radiant Wax Polish instead of AIO because i like the shine better and is nearly half the cost. It does remove light swirls but nothing more than that. I use the bodyshop compounds and more aggresive polishes for vehicles with heavier swirls and scratches. Provides good protection and is great when topped with Liquid Hardwax.

Only drawback I see is that it stains some of the soft, black trim. But this is prevented by doing edges slowly or taping the trim before you start (especially if you are going to be using machine).
