I used 3m compounds all the way down to the Ultrafina. I cant imagine anything being slicker than it. But, I didnt think ultrafina would make a big difference until i tried it out. If you have a compound you think id be impressed with as a last step, Ill try one out. My car is black so i use ultrafina on a buffer b4 shows. But, what would be good "in the mean time" product. Buttery wax? Spray detailer?
