Paint info:

• This centre cap is made from tough impact, heat and chemical-resistant plastic that can easily be painted, which will make them look even better and also help them to be more resistant to the elements. 
• DIY spray can painting is simple and can have great results if done correctly.
• First you mask up the area where the O-ring is, as you don't want to paint that.
• Plastic primer goes on next, we recommend Tamiya spray can.
• Then apply paint colour of choice, again we recommend Tamiya as they are the best quality and finish with a massive range of colours available.
• Clear coat to finish will add some depth and extra protection, Tamiya have this covered also.
• Or, alternatively, you can take it to your local car painter, tell him its plastic and have them paint it in 2K for the ultimate paint finish.
