I have found that after t he SWR, polish, I use 3M hand glaze before I put on wax or sealant. There is no protection in Glaze its for show room cars that you want a real high shine. The sealant/ or wax over the top really to me gives it a great pop.
Thats what I'm talking about if you have done your homw work, the glaze being part of that. The wax or sealant will pop up nicely. I've used this process many times and it seems to get about the best results
