I'll give another shout for Natty's waxes over the AG HD. Gives a superb finish imho and responds very well to layering (which also significantly boosts it's durablilty as this isn't a strong point of Natty's). Can also be used in direct sunlight on warm panels.

A couple of shots of Natty's 'Red' version wax on my 2 (as I always say with these things though, the wax is only accounting for 5-10% of the overall finish - the rest is down to the preparation work i.e the polishing stages):-
