A - Exspensive
B - Damage.
I have a polish car wash 5 mins from my house, then there's another 5 mins from that, another 5mins from that etc, there everywhere.

If you really are bothered about your car looking good bud, do it right I can understand and feel for you not having time etc, I've had many occasions like that, that's when I go to the Polish.
