Used to do complete details on full size conversion vans in six hours. That's a lot to wax and a lot of interior to clean and shampoo. Don't know why it took you six hours just to wax a full size truck.
Shouldn't take more than a couple of hours. I don't think it has a lot to do with the paste wax, but how you're putting it on and more importantly, how you're taking it off.
