We have heard that Safety Seal (North Shore Laboratories, NSLSales) Peabody Massachusetts, is no longer in business. For customers that have tried to contact Douglas Dunsmore, Debbie Haskell, or anyone at 978-531-3044 (9785313044) NSLSales and have been left without a supplier of Safety Seal tire repairs and Safety Seal kits, we should talk. Many years ago, we were a major supplier of Safety Seal.  In 1987 we developed BlackJack and it has proved to be one of the best tire repair products in the world. It may be just the product you are looking for. Please give us a call. 816-872-1158 or email us at
