I am planning to paint a fiberglass Therma True door a cranberry red to match a "wineberry" Anderson screen door color. I think I've heard something on here about certain reds fading, others not as much so. What do I look for when choosing the color? I'm planning to use Duration in a semi. The door is on a covered porch, but it does get morning sun.

Thanks for any help; Faron, I especially appreciate your input--you do a nice job of putting technical stuff in everyday terms!
