As part of my regular maintenance, I use a cleaner wax and buttery wax combination.

My latest application:
1. Washed with Meguiar's Ultimate Wash & Wax shampoo;
2. Waxed with Mother's (liquid) Carnauba Cleaner Wax; and
3. Topped with Collinite Marque D'Elegance 915.

All applied by hand, with the 915 curing time of 45 minutes.
