I just did my new one so here is what I used:
Optimum Power clean/dawn strip
IronX gel soap
Menzerma 4500
Optimum car wash soap
Distilled water/IPA
Opticoat everything but glass. Everything with paint or plastic on exterior including jams, under hood, trunk lid gets coated.
Tires get Wolfgang tire gel
Stoner's Invisible Glass
Optimum Power clean at 10:1 on interior
Pinnacle Black Label vinyl and leather coating (like this stuff)
When my 54 year old back stops screaming at me, I'll pull the wheels and Opticoat them also.
I went way heavier with the opticoat than is my usual practice because this is the darkest color I've ever done and it's much easier to see high spots. I actually had to over apply on purpose to get streaks that didn't flash off within 2 minutes and then it was easy to even out with my new best friend; the Lake Country coating applicator.
When, after 14 days of undisturbed cure time, I washed it, I used Duragloss Aquawax as my drying aid. Wow, what a shine!
