here's what i would do...
1. Meguiar's #62 shampoo/conditioner
2. Meguiar's Clay
3. Meguiar's Premium Paint Cleaner
4. Meguiar's #7 Show Car Glaze
5-15. Meguiar's #7 Show Car Glaze
16. Meguiar's Premium Paint protect
that's just the exterior stuff, and I won't bother naming all the little chemicals...see the link in my sig for what the end result looks like
