I am going to purchase the GGR6" as my first buffer. But I'm over whelmed by the choices in pads and kits. Which kit is the best starting point. I have. 38' 5th wheel coming that needs to be waxed. I also have 3 other vehicles that it would be used on. 1 is new and the other 2 are in good shape. With only swirl marks etc. I have some products already so mainly looking at the DA and pads. Thanks.
