Well, this sounds simple but I'm perplexed enough to ask for advice.

The patient is a standard metal five-section rollup double-car garage door.
After 15 years, it is starting to look somewhat faded. This week I had major
stucco work done on the house, and some of the contractor's material got on
the door. When he washed it off, it left obvious huge streaks and
discolorations on the door. I'm not faulting him - the door was due for
repainting anyway.

But I'm not sure what to do. Several inches of each side is, of course,
covered by the framing of the house. Only a tiny portion of the top section
is visible from the outside. Presumably I want to paint the entirety of the
door, not just the visible portion. Rolled up, there isn't much room between
the door and the ceiling.

I'm not anxious to have the door removed temporarily - there's no way I'll
fool with torsion springs.

What's the "correct" way to attack this problem?
