Motorsport Alloy Colour

One for those who like the finer details !

E36 original Motorsport Alloys, I have to refurb both rear wheels and they have to be competely stripped down to bare metal to get the job right, as a previous refurb attempt was pretty poor. Does anybody know what was the original shade of silver that would have been on these wheels ?

It will obviously cost me less to just get the two wheels done, but don't want to look a spanner if when finished they are a different shade to the fronts.

If all 4 are to be done, it's diamond cutting time, which although the business, will kill off the exhaust fund.

Any help appreciated.
