- compress - thanks for your note and reference

- ferdman - you too. I think many of the W124s have a bit different paint scheme. In other words, yours sounds like it has have a BC/CC system on the body all the way down to the lower bumper. I appreciate you taking the time to respond.

- dean - yeah, this is the information I was looking for. You're exactly right. The lower gray on my polar white sedan (0149) is definitely BC/CC. I haven't yet determined what the color code on my lower gray area is (from MB), but according to paintscratch.com, the color should be "Marble Grey (matt) Clearcoat (7201)". But to me, no way does this look like a clearcoat. I actually removed a small chip from my cracked bumper - and it sure looks like a thin piece of single stage eurethene to me. BTW - paintscratch.com wants $115 for a quart of basecoat and $40 for a quart of clearcoat. The thing that's strange about their system to me is there is no mention of reducers or other agents necessary to mix with what they provide you.

You did hit the nail on the head. It's a matte finish. But I don't know why they would spray a 'matte' clearcoat. The thing is, if I do go to a PPG system, getting all the right colors needed to shoot the lower front/rear bumpers might get pretty expensive if I go to a BC/matte CC. Like your thoughts on this dean. Thanks!
