You can sand acrylics? I think I had tried that once but never had any luck....I thought it cured too hard.Unless you want to re-prime and re-paint the whole thing, don't strip the paint. That will only cause you a whole lot of work, if not a disaster. Wait until the run has completely, thoroughly cured and then sand it away with a sanding stick, not sandpaper. You want to remove the run only, so use something flat and easily controlled. Finish sanding the run and the surrounding area with 400, 600 sandpapers and then re-spray.
