In terms of kit:
Air compressor (can rent from HSS etc), good quality spray gun, masking tape, plastic sheeting, a very clean dust free environment, thinners,primer, whatever coloured paint, laquer if the colour is metalic/perleacnt , loads of wet and dry sandpaper, infra red lamps and protective gloves /mask/ overalls and sh*t loads of patientce.
And of course, you need to know how to spray paint properly.
Id go to a body shop if i were you. If you dont have the kit already itll probably cost you over half of what the bodyshop will charge.
