As thick as a nickel, the first couple of bits of paint came off with my fingernail. That thrilled me, as I thought with just a little effort I'd be able to rid this plaster ornament in my guest room of more than a century's worth of obscuring finish and reveal its original detail. Of course, there's no such thing as little effort in an old house. You see the extent of what my fingernail could do. The rest has been a whole lot tougher to remove. Anyone know of an easy way to remove paint from three-dimensional plaster surfaces?
