I washed using these steps:
CG Matte wash with foam cannon,
pressure washed,
another CG Matte wash foam cannon application,
two bucket wash (CG Matte wash) with grit guards,
pressure washed,
dried with leaf blower to remove water,
used micro fiber towels, brand new and used 12, to dry.
Happy...
as soon as I purchased it the dealership pushed the PPF on me. I felt it was the right decision but that's before I knew Toyota owners manual stated not to cover it.
