Hey any ideas welcome I had 5 metal frames blasted two months ago, all of them from very old pianos. He used sand -- tons of it and the job was done quickly. We protected or avoided the agraffes. I am filling them in the old-fashioned way and that is with chalk and yellow ochre stirred up with French polish (shellac and alcohol). You can do it with a camel-hair mop (brush) or spray it on. I prefer the mop. How many coats you need will depend on the quality of the casting, but two or three is usually enough. It is child-play to cut down, wet or dry. I also finish using a shellac/alcohol medium, but that's just me. Whatever you finish with will adhere to the filler without problems. Frames done in this way can look beautiful after 150 years. The same can't be said of many other finishes. JD
