I'm not sold on coatings. I only used Gloss Coat due to ease of use. I'll be happy if I can get one yr out of it. Some of the better spray sealants on the market are so easy to use and last a minimum of 6 months now. Ex - Griot's 3 in 1.
Optimum is one of the few, if only, companies not tripping over themselves by releasing redundant products.
I did notice some self-cleaning this weekend. It rained heavy Friday and I drove down to Cape May Saturday morning. Very little dirt stuck to the truck. Looks very clean for what it went through.
"The new Optimum Gloss Coat was re-formulated for increased ceramic polymers that improve it's scratch/mar resistance, UV protection, and chemical resistance. Increased release properties allow it to shed dirt and other contaminates more easily, staying cleaner and making washing easier."
