Property me with this product on my car the brake drums varnished (3 layers). Between the layers I waited 1 hour each, then after the last layer 4 hours. After that I did the drum again mounted on the car and not move until the next day the car. Am now already driven about 3000 km highway and city traffic and the paint keeps super, still looks like shortly after the paint :). Therefore, 5 star!. What I also have to say is that the spray head is very good, he atomizes the paint perfectly and so I could even who has never painted achieve a result that is a painter just worthy!
Addendum (22/05/2013):
Still looks like the first day until now been through everything whether carwash, wheel cleaners or steam jets of paint keeps super!
