Try to scrape most of the foam off, then scub it down with a rag with lacquer thinner. Keep using a clean rag and it may take some of the paint off. But it will remove it. If you are going to put more skins on you do not need to remove the sticky adhesive that is on the stand after the foam is gone. If you do take it all off, repaint what needs it and re apply the new skins. Be CAREFULL not to touch any other parts of your stand with the rag or your hands that may have the adhesive on it or it will be sticky too and you'll have to clean it as well.
