I love the control this product gives me. It does take time to dry, so you have to place the project in an area that it will not be disturbed for a while(24 hours according to package directions to fully dry) 3 to 4 hours to set up firm enought it will not squish around. I have found. I don't mind doing this, but if you don't have that kind of time this may not be for you. I will definately buy this again.
