Wul,

What's the deal with clay bars? When would you use them, and what are they for?

At the moment, my routine is as follows:

Wash car with two bucket method and sheep mitt (must have been a run on those recently...)
Wax with Megs (NXT on order), last waxed 1st week of January.

Now, how oftern should I be applying wax to the car, and where does the clay fit in?

Cheers.
