1. I hand wash every weekend (exterior). I clean the interior when I feel like it needs cleaning already .
2. I wax twice a month (sometimes 3x a month). Rule of the thumb is, when water stops beading, the car needs good waxing.
3. Meg's Gold Class. Liquid wax, spray wax, detailer. Porter Cable 7424XP.
4. I would do a cycle of Wax -> spray wax -> detailer, on consecutive weekends. I bit overkill maybe but I live in the desert with the summer sun and dry heat..and a black car.
I plan to clay and polish when my baby turns 1.. then once a year thereafter.
