I ran across this and thought I would share it with the forum. There are some people using this product and claim good success with it. For us engravers and woodworkers, where we can't always use a stock coated product, this could provide a solution. I have purchased some of the clear and some adhesion promoter. I'll post some results when I get it. It costs about $25 a can, but says it will cover about 20 sq ft. One guy said he had coated about 50 just regular ceramic tiles he got from Lowes. He paid like .25 for the tiles, so that puts him at about .75 to $1.00 ea, I think they are about 3 times that from suppliers. You spray this stuff on, let it dry for 10 minutes, then stick it in your oven at like 320 f for 20 minutes. Anyway..here is the link. This is in the UK but I got mine from Transfer Supplies in Utah. http://digicoat.com/
