Mirror=is painted at the factory. Go to hondapartsdeals.com
Bumper=must be painted by a dealership($$$$$) or a good auto body shop($$$).
The bumper can be purchased at hondapartsdeals for ~200 + S+H.
A better auto body shop will order the part for you and paint it on the premises.
There is also eBay, but condition and availability is a hit or miss proposition.
