Polycarbonate paint actually etches into the plastic and gives a good finish. No preparation needed at all, and if you have a clear or smoke hopper you can spray the inside and get a great glossy finish on the outside.
Tamiya produce a range of this paint, in a wide variety of colours, which you can get from most model shops or the web.

Usually, with the paint used for RC car body shells its painted on the inside, the clear shell gives the gloss finish and the paint itself is quite matte. You key the surface with really fine wire wool, until its like a dull opaque finish, then wash it in mild soap, rinse and dry
Whatever you do, use a paint designed for plastics, or it won't adhere and flex with the hopper shell, leading to cracking, chipping or peeling of the finish and make sure the shells are really clean and dry.
A local model shop should be able to help with selecting the right paint and any masking tape etc you need.

also as a little tip andy u should use after spraying a few layers of paint over ur shell u should try and use some clear primer to give a very glossy and shinny look to it.
You spray hoppers on the inside (just like Nitro/electric car shells) so clear lacquer is a waist of time. (Lacquer is the last coat so you will not see it being inside; the first coat is the most important.)
(No need to key the plastic at all just make sure it is really clean and dry, keying the surface will lead to a dull finish. Don’t forget you see things in reverse so the inside surface of the hopper must be real clean)
The trick is for the hopper to be real clean and dry, spray a number of very light layers (not heavy ones) and lightly dry with a hair drier between coats. By lightly heating with a hair drier this will give the paint a shinny gloss finish.
