The name of the color is Cloud Silver.
Honda sells Cloud Silver Touch Up Paint in 12 oz rattle cans through their
Power Equipment dealers (mowers, tillers, etc.). I have never heard of it being available at their motorcycle dealerships, but if you give them the part number....who knows ?
The Honda part number is 08707-NH35M.
It is not cheap. Costs about $17 - $18 per 12 oz. can. If you can't source it at a local Honda Power Equipment dealer, you can order it from Plano Power Equipment and several other places online - however, shipping is high for paints & chemicals.
Here is the link:
Plano Power Equipment Online Store - Honda Paints, Fluids, Lubricants, and Fuel Additives
There is also a PPG paint code that supposedly matches the Honda color. The PPG code is 33778.
Hope this helps.
