I second this process... I do the exact same steps, however, I use their white wax rather than Petes. All other products and processes I replicate.No clear answer for sure. Too many great options, just gotta go with what works for you.
For me I'm using:
sealant - Chemical Guys WAC_118_16 - JetSeal Sealant and Paint Protectant
wax - Chemical Guys WAC_300 - Pete's '53 Black Pearl Crystal Polymer White Carnuba Paste Wax
detail spray - Chemical Guys WAC808 Hybrid V7
Yearly - After prepping the paint (wash, claybar, buff with Meguiar's M2 Mirror Glaze Fine-Cut Cleaner) apply 2 coats of sealant 20 min apart; wax; detail spray.
Every 6 months - wax; detail spray
Every wash - After drying with electric leaf blower detail spray.
1. WashMr Monte you apply the sealant coats prior to the wax? Im not at your guys level so school me.
