Hi guys, I am just wondering what the experts on here think that the practical approach is to painting the PelletVent Pro exhaust system. Honestly, we are buying the galvalume option (not painted black), and had just assumed that it would be used as is, without having to coat or paint it. I had always been under the impression that galvalume is relatively corrosion resistant and also doesn't take paint very well. But then, in reading Duravent's installation manual for the PelletVent, they mention that they recommend painting for prolonged usable life. So, do most people paint their pellet chimney system? Is it even worth painting? I was considering using something like Rustoleum Clear Engine Enamel spray paint, but am not really sure if or how the galvalume should be prepped before painting. Thanks for any help.
