Casper, A plastic primer would be good on all plastic parts, Make sure you prepsol all the plastic before touching it with everything. Then do a few coats with the plastic primer. Once dried get a spray pack with the colour of your choice. And do another few coats. Then follow up with some nice clear coat. Just make sure everything is super clean and dont rush the dry times. Make sure everything is completely dry before doing next coats. I have done a lot of plastic in the past and this has worked the best for me. Come to think of it I might have to spray mine now aswell.
