Masury satin black seems to be an exact duplicate of the factory finish on older 911 suspensions, engine tin and the like. From what I've seen, I like the look better than the SEM trim paint or the Wurth. Problem is, I can't find a source, and I can't remember where I bought my last spray can of the Masury. Does anyone have a suggestion? Alternatively, woiuld someone say that the SEM or Wurth are better? Thanks. Tom
