BronzeShield is a high performance clear topcoat for bronze art and architectural conservation. It is formulated to be selectively-removable using a non-toxic paste remover safe for bronze surfaces and patinas. BronzeShield is available as a two-component kit with a variable surface finish, depending on the needs of the conservator. It also comes in handy aerosol matte finish only. The selectively-removable polymer was initially developed at North Dakota State University with a grant from the National Center for Preservation Technology Training. Can be used alone or with wax.
