Need the lower grey paint code.

 

Check out my posting on topic.

The paint codes should be similar for 1999 and 2000 LS400.

Had incredibly good service and assistance from Automotive Touch up Paint.

Have the exact same issue with lower bumper paint flaking off..

My Jade Pearl.Silver 1999 has unique color cladding (from 1997-1998) and they properly directed me.
