What is benefit of sealer before wax?
I am new to this, so this may seem like a basic question. I most recently used some Mcquires liquid wax on my car it it looks good. I just ordered the souverain signature series II paste wax and will use this the next time I wax. Should I get something like the Klasse AIO or a polish of some sort before waxing? Will there be a big difference. I'd like to have the best, deepest shine possible. My car is a black BMW. Thanks!
