Stray brushmarks removal from Bootstripe

[Tarheelrod]

I'm almost finished with a three yr restoration on a Herreshoff Eagle sailboat (Which will be for sale BTW) and I'm about to put the last coat of paint on the hull using roll and tip method. I didn't completely tape over the white boot stripe and now I will be dealing with a couple of spots where the new black one part polyurethane paint is on it. Any suggestions on what I can use to remove it. What about the "liquid of choice" and using it to wet sand the areas with 600 grit paper to see if that will do it.
