I keep trying different resins, and I keep coming back to this one. It is easy to work with and part A is not as thick as some others. This makes it much easier to work with and to mix. I also have not had a lot of problems with bubbles with this resin either. Not even the microscopic ones. Especially if I use in combination with a heat pad while curing. I wish they sold it without these kits, but that would be my only gripe is that I can’t just get a gallon of part A and part B without buying it this way. I don’t need all of these extra supplies and pigments. However, that would be useful for someone just getting into this craft.
