I did purchase a DA for the cleaning process. With that it took most of one day to do all the cleaning and Windex spray after. The coating process was smooth for me and took about 4 hours. I came back later and did all the exterior glass, plastic and cameras.
I used the process from Out of Spec detailing for the Pan the Organizers ceramic coating and love the results. I had my truck in to a service center and saw it parked next to 2 other Cybertrucks and the difference was shocking. The coating process with BKF makes the truck look so much brighter...
Find that I check sentry cam clips more often now. It great to see most are just passing by, some look out of curiosity, and then you have some great ones like these kids.
