I'm all for doing it yourself but by the time you buy paint, cear coat, sand paper and your time you would be far better off to pc. It,s also far more durable, especailly for those parts that will get wear and tear. If you still want to paint I would start at about 80-100 grit and work down to 400 paint with a sandable primer then wet sand that with a 600 grit, paint your color then clear. I'm not a pro painter, that"s just what has worked for me in the past.
