DuraGloss 105/601, topped with Collinite 915. This is probably the best looking, longest lasting, economically priced combo I've ever tried. Collinite 915 was featured in a thread on here when it came in second in a wax shoot-out, and was rated higher than the third place $8500 wax (I think that was the cost).
Blacklight, topped with CG 50/50 (or Pete's), topped with V7. This combo still turns heads.
And or course any combination of Blackfire Whiplash sealants/waxes
