I was going to schedule to have my dealer paint my antenna for $60 but have found what may be a better deal. This company is running a $25 special to paint Sirius antennas. The only big problem is you have to ship it to them and will be without it for a few days. Here is the info from them.
we paint the factory antennas as well. Even if it is a metallic color it won't affect signal strength. The only antennas we can't paint are the ones that are factory installed, i.e. a lot of the GM cars. We paint the Mercedes antenna. As a matter of fact if you want to save money buy the antenna from us or on Ebay and you'll save a lot of money over what the dealership would charge and it will be painted. Soon the dealerships will be painting them but in the meantime.
We paint the antenna the day we get it and send it out the next day.
From the time we get the antenna to the time you get the antenna back
would be about 4 days total. Feel free to ask any other questions to
