Thanks for the paint recipe. I have that color that I can use to match and have the color code. But any PPG store I have been to doesn't want to mess with guessing on how much flattening agent to add. This recipe gives the exact amount of DX 995 to add and now should be no issue. I am about to refinish the underside of my W128 220SE and want to get it right. The Ponton coupes are black underneath BTW.
Thanks again.
