A waterborne acrylic coating was applied over a washed and tool cleaned zinc/vinyl system as a maintenance overcoat. The coating has several positive characteristics in that it is “user friendly”, substrate tolerant, develops good adhesion quickly, and is environmentally friendly. There were some issues concerning quality of work in surface preparation and application and in the fact that on two locations bubbles developed in the newly applied coating. The cause of the bubbling has not been determined.
