Nimbus Gray shows up as a valid paint callout for Honda on the Odyssey mini-van. Maybe it's the same. If it is you could probably get that at any auto parts store or the Honda car dearlership. If not try going to a paint and body supply and ask then to mix up a sample based on that callout for your bike. A really good automotive paint shop can mix up paint with a sample like a side cover off your bike. Our local guy can even do spray cans that come out closer than touch up paint that you buy off the shelf.New to the forum just curious any1 know if you can find original paint "Nimbus Grey" for the 83 gl650? Just got 1 and want to restore it. Also how the heck do you pick a profile picture and set a signature? Just having a heck of a time trying to find it.... Took computer support at a local college. Sad.
