This thread is the reason I am fearful of buying an older home. Who know what has been done and how it has been done. I think I'm with bowdog on this one, makes my head hurt too. Such a simple fix yet people make it so complicated. It's easy! Quarter size hole, put a wine cork in it with super glue, drink the wine while the glue is setting, then paint over it. Walah problem solved. (This is not really how to do it, figured I needed to write this so the bashing didn't commence)
