On a garaged car and one that receives routine pro washings and lots of care? I don't think so. Had it done to my Alfa, and frankly seemed to attract more dust than traditional wax. I might consider it if the car gets neglected or abused, but otherwise I don't see it.
Considering my car gets an annual paint correction and I never touch my paint I opted for plain old wax on my Caddy. Just as good. Saves lots of cash.
