I have used a can of stain for specific projects. The product is at least 40 years old and always served in a spectauclar way. Now the can is empty, Pittsburgh Paints no longer supplies this kind of medium. I have been told that it was made using linseed oil rather than today's carriers. Testing of more than 20 available products has convinced me that to continue to achieve past results, I need that "original" product. Does anyone know of a company or specialty shop that can make a linseed oil stain?
