I prep all cars in the spring with 4 coats of Black Fire, then layer two or three coats of
Fuzion over it through the course of summer, for a nice look.
For winter I just put two coats of Collinite 476S on using my
Flex 3401, easy to use, looks real nice and is tough.
Living in the North East and having my Black vehicles live outside year round, I have no problem layering many coats of protectant on the finish. It is the easiest step to do for me and the Collinite always goes on last.
