[Perfectlap]

^the guy on Autopia has it trade marked. He calls it 'the perfect shine".

Once you put that Carnauba wax over the acrylic Klasse sealant you have to strip the whole thing down again if you want to add more sealant to add further depth to the appearance of the shine.
Carnauba or "wax" over Klasse sealant is nice depending on the color, I think its overkill on a black car. But can make a big difference on lighter colors like Silver, red and yellow.
Some think highly layered Klasse sealant looks like a candy coating and a bit too showy, kinda like people who use those greasy looking tire dressings.
