the key to a good paint job (no matter what your painting) is the prep work, use a "scuff pad" to remove any of the shinny white finish from the factory, it should be dull when you start, next completly clean it with a degeaser, use rubbing alcohol if you must, make sure not to touch the surface to be painted with your fingers after cleaning (your hands have grease and oil in them) read the directions of the paint, follow them accuratly.
