I have always been using the spray cans of Cermark for our products but one item we are doing now just needs a small line of text engraved on it so I thought I'd try the Cermark tape. The material we're working with is brass and the spray on Cermark has been working perfectly but I tried the tape today and when it was done I pulled the tape off, cleaned the surface with water and nothing was there. All the black Cermark washed right off.
Its my understanding that the tape is the same stuff thats in the can so I'm wondering why it didnt work.
