I tend to prefer Klasse twins with SG x5 and no wax topper with the exception of Souveran on black. Once SG starts needing some kick in the looks department after I already have 5 layers, I start using Aquawax to refresh the look. AW gives a very good approximation of SG, not quite as eye-popping but only by a miniscule amount. That seems to be the opinion of all that have seen my cars.
The waxes that I have tried as a topper for SG all lessened the wet nail polish look. While NXT paste, S100, Meg's GC, DWG and Souveran all looked good over SG, only Souveran improved on the overall appearance of the car. PS just took black to another dimension, giving up some gloss for glow and depth (lots of both). PS just looks luxurious. But I get the most stares when the car has AIO/SG only.
