I have a set of wheels preped just like the instructions say, as well I watched the video. I put a pipe cleaner with some graphite on it and ran it in the drill at medium speed but i am not sure that did anything. I see things on other threads about using a walgreens q tip shaft to burnish the graphite in the bore, will this mess up the polish job? I thought that the shaft would be a tight fit and mess up the polish job and or the bore. I want to pull the wheels and do this right and see if i can pick up any speed on the boys cars.
