Durable Gloss black finish for fog surrounds

[Tfsi_Mike]

What would be the most durable gloss black finish for my plastic, honey comb fog light surrounds?

Ive thought of powder coating (not even sure if its possible with plastic)
Painting
water transferable printing (WTP), the method used for carbon dipping

Im all questions lately!  Trying to squeez in the mini mods before TFSI_Jnr arrives and I have another modding dry spell   
Thanks in advance

Johnstones (paint suppliers) do an anti graffiti type coating which Ive used and its very smooth but cant remember its exact name. It wasnt a deep gloss though so might not suit your needs.
