Cast Iron sculpture restoration 

Letter 6029 . I am looking for a way to take the rust off of some cast iron sculptures and to put a finish on them to protect them from further deterioration. The largest piece that I have is a bust heroic size. Greg P Grant fine arts - B.C. Canada . There are at least 2 ways to solve your problem. One is chemically the other abrasive blasting. There are some excellent rust stripping products our on the market. It sounds as if you would need to get at least a 5 gallon container of a good product, immerse your sculptures in product from 3 to 5 minutes, then hot water with some form of rust inhibitor and let stand before applying final finish coating.Second method would require the use of blast equipment. Media which would leave you the most natural appearance of sculpture would be dry organic walnut shell or corn cob. AF Kenton Nova Finishing Systems Inc. Huntingdon Valley, PA
