I typically use a simple hard shell turtle wax, but it can be pretty time consuming. I always see spray wax on the shelf, but never thought about buying it. How well do they work? Is it worth switching to from regular wax which consistently gives good results, but as I said can be very time consuming? The one I am possibly considering is one from the Mothers California Gold line. I also want to try their clay bar system, but that's different topic for another time.
