Treatment for acrylics on glass , permanent bond?

[QTs]

Posted this in acrylics forum as well, but thought this forum might have some expertise in the subject.. hope you all don't mind.

Anyone have experience painting onto glass?

I'm trying to get a way to apply acrylics and gouache/watercolors in a fashion that will bond with the glass permanently, using a polymer that has no texture.

Was going to use GAC200 through an airbrush, but the site says that it can't achieve a permanent bond with glass.

If anyone has other suggestion for a surface that is also transparent and smooth, it would work also. Maybe acrylic sheet, has anyone tried? Suppose it would be far less scratch resistant though.. and a bit less clear.

For glass you are going to have to sandblast it or abrade the surface some how. I like sandblasted surfaces for painting because it is an even texture. Most glass painting is done with oils but some people do use acrylic. The fact of the matter is that the acrylic will not stick permanently no matter what if there is not some kind of texture. It's the same with plexi, which is why people use glass and plexi for palettes. A finer grit, say 220 or 400 still allows for a great deal of transparency, the finer the grit the more transparent but the less the color will hold.

Sorry, probably not what you wanted to hear but it is what it is.
