I have had good results with Red rocket (applied along with graphite by dipping the RR coated applicator into John's graphite). Let it dry for 10 minutes blow off excess and then let it dry for 15 minutes. Buff out the bore with fluffy pipe cleaner. Blow off the fibers stuck in the bore (if any). Now burnish a layer of John's graphite using a 9200 polished rod (One piece pine car rear axle will do). Pass the metal rod through the wheel bore, add graphite from both ends, tap to spread and then hold the rod snug with clean cloth to prevent graphite falling out from both bores and roll it on a clean flat surface. You are grinding the graphite and forming a mono layer inside the wheel bore. After 10 minutes of rolling blow off excess graphite from the wheel bore and carefully clean the wheel tread with alcohol soaked bounty. There should be no graphite on the tread at all.
Graphite burnished like this is good for at least 10-15 runs with no loss of speed , no need for adding graphite before finals. But if you do make sure you crush it in by rolling the car on a clean surface.
Good luck.
