Thanks, I'll look into it more.
Geeze, flamed on my first post! I thought I was having sense thinking about that before anything else..
I tried a search but couldn't find much about this. Has anyone done this and had problems with peeling on any surfaces? The ductwork can get pretty warm, would this create problems with the paint?
I'm assuming I should use a different kind of primer since i'm painting the ductwork wood and wires. Any recommendations or should I just go by what the paint store says to use?
