We are in the middle of trying to repaint our house on the outside. I have a steel garage door that is southeast facing that we can't seem to get any paint to stick to well. Every time we paint it, it bubbles off the surface in patches over the next few weeks. We have tried priming it, sanding it, stripping it with citristrip, wire wheeling the door beforehand, and nothing really seems to stay. Does anyone have any ideas for what we might not be doing well? #home
