Welcome to the Flames Board tof811.
If they are fairly small runs, sometimes what I do is break a very small piece of paint paddle off, wrap some tape around it (kind of softens the wood), then I wrap a piece of 1200 around it and use it "wet", Then I finish by lightly sanding with 2000 grit (no paddle). Then buff.
If they are pretty bad runs, you may even have to use 1000 or 800 grit.
Tip: If I have to use a course grit. I will tape off the area around the run so my paper does not hit the "lower" portions of the run.
Wow...do I sound like some type of "run specialist or what
