I bought a big tub of this Flex Paste years ago and it's still as good as the day I got it. The great thing about Flex Paste is that you can use to create so many different things. I use it to make fake snow on my craft projects and as a filler on areas that aren't smooth enough; and once it's dry you can sand it. When it's still wet you can sprinkle glitter on it and it will stay on, and when it's dry you can paint it with acrylic or chalk paint, and I presume you can use other types of paint as well. My Flex Paste is a very useful tool that I use all the time for lots of different purposes. It has gone up in price since I bought mine, but it's worth it. Thanks Woodland Scenics for a great product. Oh, and it lasts forever too.
