I am trying to seal a vinyl cutout to a dish. I saw online a person painted something on top so that the vinyl wouldn't peel off and I can't seem to find what product I need to use. I want to be able to cutout monograms etc and put them on some vintage dishes I have. I have used Blair spray, liquitex and several other sprays as well as heat and none of them make the vinyl not peel up. The one I have was given to me as a gift from the etsy business, but all she would tell me was that she didn't use a spray. HELP!!! Does anyone know what product I need to use. The dish I have you can't see brush strokes or even tell where something was put ontop of the vinyl, it just has no edges where it can be peeled off.
