I like this product very much and have been using it for year's to make all kinds of window clings. I just wish the Plaid company would bring back more of the shimmers and sparkle type paints. However,I have found you can add your own sparkle with glitter..I use many different types of glitters and my window clings are beautiful.
So far I really like this, much better than Das clay. It has no unpleasant odor and is very smooth, takes detail well. Has a distinct leather hard phase where you can work that way, really neat. Hasn't been long enough to really test finished strength though as that takes two weeks (it's dry though in a day or two).
