Sand the spot down and spray POR 15 over it.

The least expensive and fastest option. Since a can of paint and tools is going to cost 50 dollars and is no guarantee it's going to look good or work.

Replacing the whole door is a bit extreme for what sounds like a ding.

Not really. A whole door assembly w/ hinges that comes off a junkyard car is going to take an hour to install and look normal. Cleaning, sanding, prepping and applying three layers of paint. That is after the dent is removed. More than two hours and like I said; going to look like shit since there going to be a spot of fresh paint.
