I have a fiberglass garage door in white, and while I love the look, the insulating qualities, & light weight (easier on the opener's motor than heavy wood), I wouldn't want it in a faux wood look. When I researched entry doors, it seemed like the big complaint about wood-look fiberglass is that it fades after time and needs to be restained periodically. I wouldn't want to do that for a big garage door. The gel staining wouldn't be too difficult, but applying the UV resistant poly coats would give me pause. A wood door's maintenance would be just as demanding, and wood is heavier (needs more powerful door openers) and is prone to warping (which is why we got rid of our old wood doors). I would think a steel door in a faux wood finish would have the same maintenance issues as fiberglass. It's not so much the door material as the coating on it -- stains & poly don't stand up to heat, sun, rain, & snow well. So just as long as you know what you're getting into. A wood look door may well be worth the effort & expense to you. And maybe your DIY skills are way better than mine! Wood garage doors seem to be the fashion now. Over in Advice, many are asking how to update their homes. The popular answers are 1. Don't paint the brick, it's a maintenance hassle; 2. Replace your garage door with a stained wood door. I question the responses because in my experience, it's the opposite: stained wood garage doors are a maintenance hassle, but painted brick is not if prepped well (is in good condition, sparkling clean and bone dry before painting).

Are you painting because you want a color change or is the tan finish scratched or worn? Anything painted will, inevitably, need to be repainted. If you do not dislike the tan, repainting it tan will mean it will look less worn the nest time it needs painting because any original paint revealed by any peeling of the new layer of paint will be the same.. Consider choosing the same tn color as the siding of your home or a color you like from within any brick or stone you have in your exterior walls -- or, if your windows are trimmed in white, you could use white.

I believe your garage door is only warrantied for acrylic or water-based paints. No spray paint. Get a good acrylic primer and then just paint the color you prefer.

You may not mind the initial staining and sealing, but I believe you may tire of this chore in a few years. I'd opt for a woodgrain effect/fiberglass or follow Clopay's advice. Otherwise, find out what you'll pay to have the doors professionally maintained, and multiply that figure by the times required over the years you plan to live in this home.
