i just used that stuff today, and my arm is about to pop off from whiping on and off, feels like that stuff doesnt dry untill a little bit after, even though the bottle says no dry time. What sucks the most is so far with one layer it just seems like normal wax, havent got that nice shine u have.
I think its safe to say, a buffer is HIGHLY recommended in using klasse, unless ur ready to get a nice arm work out or get a friend =].
