    Hey folks,

    Almost done painting my hillclimb racecar with EW single stage urethane. Wasn’t planning on wetsanding it, but I would like to buff it with something like a PC 7424 (random orbit). Any recommendations on: 1) amount of time to wait before buffing/polishing (does the urethane “outgas” for a while, or does the catalyzed mixtured cure pretty quickly?) and 2) and recommendations on a starting pad/compound?
