No, Greenouse had his Monza's powdercoated all black and then diamond-cut back to the alloy on the face. That's how all oem Monza's are finished - Black 'inserts' on Mk6 (we think) and grey on Mk5.
Mine are all black too, but powdercoated Smoked Chrome on the face and inserts but with hand-done dusted to the 'inserts', hence allowing more the black to show through and create a chrome effect. The edge between face and 'insert' is soft and graded.
