Actually, the paint on these is remarkably resilient. I have a single Hush Thrush on my son's '76 Buick, and it has a great, low, non-intrusive sound. It's been on the car since 2011. A 500-mile drive two weeks ago and a 130-mile drive this past Saturday made me appreciate that sound even more. I'll see if I can get a recording of it this week and post on youtube, and I'll link it here.
