Strictly for convenience in aerosol form and the local Napa store stocks it I buy this stuff for doing touch up and small parts. Once dry it does stay slightly tacky but protection is very good.

I normally buy 5 gallons of wax oil type product (Tecty) and use a dedicated spray gun for big areas and/or entire vehicle.
