Need a M90 paint code for back cover

picked up a battery cover from a RC 838 (exact door used on a M90) problem is it is black and i want to paint it dark grey to match my rear cabinet. anybody have a paint code for the back cabinet?

find your local friendly // trusting auto store --
you will find that the spray can tops are very accurate --
take the 1/2 dozen cans with the closest colors outside in the sunlight --
at least one will be close enough for your m90-
other than that --there is no ' stock' paint code i know of

Or you could compare with the RAL chart and order from there, any paint factor uses these formulae and they are the only way that's truly universal.

I've scanned mine in at its native size so by clicking the image, it can open to the full size and you'll see every paint code there is on there. Most greys are in the 7s but if you order from your factor don't forget to add the flake if you're doing a metallic finish.
