How "Anal" Are You With Respect to Runs in Paint?

Depends on the application.
Race ride, no real care though I’ll take some care so it doesn’t look like a hack job.

Daily driver, same as above but with some actual care in paint application. If I get a little drip, OK, maybe try and cover it up with a few more layers of paint. I don’t do resto work but a drip would not be allowed to stay.

Location is also a varying issue. Oil pan, pfst, as said above, use it as is. Unless it really bothers YOU!
