When I polish my warwick, I never seem to get it right. Do you apply a very thin amount of wax on the top, let it sit for 2-3 mins and then wipe it off with a new cloth? If not a thin amount, how much? Should I let it sit on the top for a few minutes? What am I not doing right? -I am not really getting a bad result, its just some places are shiny, some opaque, some scatches show thru differently etc... Any advice?
