Done that many times, although my garage door doesn't seem to leave much of a mark. My advice would be to forget about it.
I can definitely one-up you, though:
- I park in my garage by stopping on the street parallel to the house, and reversing in via a sharp 90 move. One time I forgot I had a utility trailer attached. The rear bumper cover took some good scratches (and the trailer's frame actually bent a bit from the impact).
- Another time I had firewood on a roof cargo tray, and was throwing it down in camp. Managed to nick one of my tail lights and crack a piece off. Glued it back in, but it's clearly visible where the piece was broken off.
- My rear, passenger side door has a tiny dent from the time it lost a fight with a 20lb propane tank.
I've had this truck for just about 7 years now (by FAR the longest I've owned any vehicle) and it has accumulated way, way more scratches and other imperfections than any other vehicle I've ever owned. On the upside, I've stopped caring about these things quite a while back, and it's a significant emotional relief. I don't care if I hit a curb, I don't care if someone nicks my door in the parking lot, I don't care if the hood adds its 500th rock chip this winter. It's quite freeing, actually.
