where do I go to find out what years there is NO clearcoat on the black 040 paint?

I don't believe 040 black ever had a clearcoat, at least on a W124.

suginami,

From Mercedes I found out the 1998 and 2002 MB c-class have clearcoat
Obviously they don't have the new SCRATCH RESISTANT clearcoat used on the latest models.

Yeah, clear coats scratch real easily, and it shows up real nice on black.
