First take it apart and clean with mild soapy water (being careful to use latex gloves so there's no human oil on the parts, and give it a rough sanding. Prime with a spray primer. Next go 3 or 4 very light coats (waiting 30 mins or so in between to let it dry to the touch) with Krylon Camo or another matte colour. Finally seal it up with a MATTE clear coat after you let the paint cure (24 hours should be fine for letting it cure). Not a regular clear coat but a special matte one that protects the paint and seals it up.
