take it all apart, wash the chrome, get all the dirt and **** off, wet and dry, id say start off at 1500 to get the chrome off, once thats off, go a litle higher, 2000 grit should be fine. once its off and its ncie and smooth, wash it again, let it dry, get the primer out, base coat, nothin too thick, wet and dry that, another coat of primer, wet that, if its lookin ok, get the paint out, give it a couple of coats, if need be, hit it with the 2000 to get rid of any imperfections, once your happy with the finish, hit it with the laqcure (sp).
Flat and polish after that..
Im no expert, so if someone who has better knowledge, please correct me
