Hello,
We have recently discovered that when Thermark is applied to Brass and left outside, the bond between the brass and Thermark breaks down as the surface tarnishes. See post below for images and details. I'm looking for a little more longevity out of the Thermark on brass and bronze when in the weather. My best guess is to apply a clear coat to protect it. Has anyone has any experience with coatings on bronze or brass? If so could you share your experiences? The brass and bronze would be either polished surfaces or matte. Or is there a another bonding material like Cermark, Laserbond 100 or Enduramark that offer more protection?
