Darren, any quality Carnauba topper will add depth and slickness. I recommend the P21S or the Poorboy's Natty's Wax. I would also try to use
Sonus instead of the Zaino as a QD over
Klasse because the Sonus will prolong the Acrylics in Klasse whereas the Zaino is a complete different formula. Sonus now also makes a QD for the Carnaubas so that can be used when you top the Klasse!
