In between washes, I've been using David's "Quick Detailing" method (wipe down with wet MF towel followed by Qd/buffing). It works great and is especially handy since PA is in a drought and washing is off limits. I've been tempted to put a coat of wax on after such a treatment but have thus far resisted. Is the car clean enough or do you guys only wax after a full wash? Thanks.
