Clear coat is not a problem. You can get 3M paint defender for 25 bucks at Walmart , whatever
Sun UV is a BIG BIG problem as Seibon ( although a very reputive seller ,reviewed by many), carbon creation (mine hood) does not provide UV clear coat (if they havei doubt they have to proudly advertise it).
The only solution now(as i know) is turtle wax + merguras that strongly advertise they provide UV protectant on their product.
keep me informed. Now i still hide my Z on a storage until i can find a good UV solution
