Saint Christophe Securite Glass Etch Mask

Saint Christophe
Securite glass etching mask for use with hydrofluoric acid paste to etch the
Saint Christophe logo on window glass. Made from mylar and has an
adhesive on one side. This mask is applied to clean
glass and acid paste is then applied over the decal mask. After two
minutes, the acid paste may be rinsed off with water and will leave a
frosted surface where the glass was exposed. Required etching paste is not available from our store.
