I have recently received a couple of different queries in regards to sealing bronze markers to keep the gold from fading, etc. From what I can concur, it would be safe to seal these with a polyurethane substance, providing they are not attached to another headstone. Can anyone shed some light here? Cindy L. (Skiles) Frie Please visit the Berrien County Genealogy Society website http://w3.qtm.net/bcgensoc/index.htm
