Go to Home Depot or Lowes and get yourself some aircraft paint stripper, some latex gloves, and a pack of 'throw away' paint brushes.

Get home, put on your latex gloves and shake the stripper can. Brush liberally on the parts. You should actually see the paint start to bubble up in a few seconds. After a few minutes, take an old rag and wipe off the 'gook'. If there is any paint left, repeat process. When you're finished, clean with lacquer thinner, dry and re-paint.
