I have the Ceramic Pro Gold on my C6 Corvette, it looks amazing. I had it done about 4 years ago and i think it has a 7 year warranty. Still looks great, i wash my car every few months because i never drive it, it just sits in the garage until i take it for a drive on the weekends. The best part is i can dry my car with compressed air, the finish is super slick. I wash with a foam spray nozzle, give it an easy scrub with a sponge, spray clean water and then use my air compressor with a small nozzle to dry the car. It takes about 20 minutes total.
Water does not stick to my car if it's clean, you can pour a bottle of water on the hood and all of it will sheet off in seconds.
I think i paid $1800 for everything including some paint correction. Car was in perfect condition when it was done and looked way better afterwards.
