This product is a little less money than the one I was using so that is why I decided try it, The resin is quite a bit heavier than the hardener so I have to be very careful about holding it steady while I pour it. It also dries quicker than the one I had been using before. There is no smell. It leaves a good, hard finish on the pictures and geodes that I have been painting. They are beautiful and the resin makes a huge difference!
