I am looking to buy this kit as my first investment to better looking vehicles, Griots Garage Swirl Remover Kit. I notice it comes with only three pads. I would like to buy a six pack of extra pads. My wifes Toyota Sienna has single stage white paint and is oxidized, but nothing excessive. I can polish it with a good bit of elbow grease using Megs UC and then Megs Polish, then Wax. Keeping it white is a different story. The paint always goes back to looking dingy. I have experimented with a Megs Ultimate Wax and the panel I did seems to stay looking good a lot longer that previously. Due to having to removed some oxidation, how many pads is a good starting point? Thanks for helping!!
