I've currently been using a combination of 3M Finesse Hand Glaze and P21S Carnuba. I just picked up a Porter Cable buffer. I plan to still use the Hand Glaze, but the P21S cannot be applied by a machine. I also got a free bottle of a PoorBoys 1-step that I don't plan on using with the Cobra. Is there a high-quality Carnuba for machine use, or should I stick with applying the P21S by hand? Also, does any use the machine for removal or does everyone just do it by hand with Mircrofiber towels?
