My first few uses of Meguiar's Gold Class liquid wax on our Super Black XE were good, but I waxed it again yesterday (by hand, like before) and ended up with swirl marks. I couldn't get rid of them no matter what. Since this is our first black vehicle, does anyone have any advice or a similar experience?

The wax was stored in the garage and we've had cold weather, but it seems unlikely the temperature in the garage went below freezing. Still, could that have affected the wax?

And would using a 'surface prep' product strip the wax to the clearcoat so I can start over?
