I bought this product to tint glass, sprayed the product on cleaned glass as directed on the can, color was great, came back the next morning, and it had faded to almost yellow! i added a few more coats as directed, and again the next morning it had faded horrible, the glass was not in any direct or indirect light. I would not recommend the product!
Purple does not work real well. I read the comments that were not real happy with the purple glass paint but had to try it. The sea glass color is awesome but the purple not so much.
