kdx200 silver paint code?

anybody know the paint code for the "silver" used on the frame of an 87 kdx200? or i guess has anyone found a stock hardware/auto parts store paint that matches? want to cover a few spots, but most "aluminum" paints are way too bright. fyi, towerpaint.com will mix an exact match and deliver in an aerosol can, but it's $15 for the paint and $9 s&h. thanks in advance. steve

it's not that it's pristine -- but i only have a couple of spots to cover -- and don't want to have to pain the whole frame to make it match...
