The Klasse Twins look nice on light colored paints.
My personal best results on light colored paints have come with Blackfire, especially with multiple layers. Besides being incredibly slick, you'll see light colored paints shimmering/reflecting extremely well. I worked on a neglected tan Taurus recently and after one application of BF polish by PC white pad and an application of BF AFPP by hand( preceeded by wash, clay, wash, etc.), the paint looked better than new.
As with every color, prep is the key to good results in the end. The best/most expensive LSP on the market will look like crap over a poorly prepped surface.
