Hi D.D - Whenever I mounted a Deerhead I used its washability as a selling point! I'd deliver the Head tanned with EZ-100 and tell them, that if it accumulates dust or other grime - you should be able to safely clean or wet it. In fact, years from now, if you want to, you can have a Taxidermist strip the cape (providing you didnt use super glue as a hide paste) off the present mount, rehydrate it and have it re-posed on a new form safely. EZ-100 is a syntan. Most hot tap water at the most attains 120 degrees Fahranhiet. Being a syntan, to cause any problems with it, you'd have to wash an EZ-100 tanned cape above 180 degrees Fahrenhiet. I can't vouch for all syntans, but I know EZ-100 reacts that way. Its a way of reassuring your customer he was getting a high quality product. The other aspect I'd emphazise, is the tanned cape's longevity. I'd always say - this EZ-100 cape will probably outlive you and me both! By the way - that 180 Degrees Fahranhiet I refered to is the temperature at which the tanning agent loses its chemical bond to the skin. It's called the shrink Temperature by Leather Tanners. Chrome tanned leathers usually have a Shrinkage Temperature of 212 degrees Fahranhiet. Sometimes even higher, if they retan the skin. However, Chrome is not a good Taxidermy tan - but a great leather for clothes and accessories.
