Built home 8 years ago and used fiberglass exterior doors. One of the doors
just doesn't handle paint very well. I guess it's because of the shade and
water runoff when it rains. In any event, the paint molds quickly and
flakes off the door. Over the 8 years, I have painted the door at least
three times. I've tried different paints and nothing seems to work
Thanks in advance for any suggestions or advice (prep, prime, paint, etc).
