STLBrian, As a followup, this is my 3.5y/o Model S that was decontaminated, polished and coated this past weekend. It was about 24 hours of total time, with about 12 of those the initial cure time between Gyeon Mohs Q2 and Kamikaze Over Coat. A lot of work! These are pretty durable and hydrophobic coatings. The Over Coat can be applied periodically as needed. Regular washes with Gyeon Bathe+ or CarPro HydroFoam.
