Well Marlene I been checking in all day to see if anyone give you and advice...I love window related things so I'm interested to see what advice anyone has for ya...

Could it be that pour-on acrylic stuff that was real popular with the DIY coffee table projects a few years back? I don't remember exactly what it is though...an acrylic resin perhaps? Folks would set seashells or coins or other trinkets on a framed surface and then pour this stuff over it. I remember a really cool table made with old costume jewelry!
Ringing a bell with anyone? I do remember that stuff did not like hot coffee cups!
I think if you had an old style window with glass panes this goo would work. The panes should hold it in place and allow you to "set" things in it.
Interesting idea, let us know what you do with it!

if that's it, my DH use to use that one my woodburing pic's. You have to mix it together.

Hmmm....I'll have to do a little more research I guess. I may not have explained myself very well either. Thanks for the help ladies!

Now there is a liquid laminate that comes in a bottle that you just squeez(sp) on...

I am familiar with 2 part epoxy resin that is poured and dries clear. This would NOT be the stuff you'd want to use for windows as it yellows from sun exposure.

I'm wondering if one could use GE Silicone II for this, the same product that some of us use to make glass garden totems. You'd have to glue items on individually as it dries fairly quickly altho needs some time to fully cure.

I might try this on the top of a "totem table" I've made. It might be improved with a mosaic china top.

I think the stuff you are talking about is called EnviroTex
pour-on Finish, it equals up to 50 coats of varnish. If you are planing on using for a outside project does not do
good outside, but works great on mosaics or inside projects.
