again all polishes and waxes are like lotion everytime you wash your car it will come off little by little. the wax protects the polish that protects the clear coat, so everytime you wash it wax comes off little by little thats why its recomended to wax your car every 3 months before the polish starts to come off and you no longer have protection for you clear coat. and every wax from different companies are the same to a certain extent. some are water base (cheaper) to a thick blob wax (expensive) but they all stay on for the same amount of time.

 

Klasse is definately abbrasive although I wonder how as well considering it is acrylic but look at what I was able to do by hand polishing with KAIO (this is my paint on it; already strike through):
