I used this for many months for epoxy resin art pieces. Even with proper ventilation, the fumes are horrible. Headache inducing. The gallon bottles are easy to store, and pour. They cure nicely. Not much working time as with other resins, but if you can get past the smell it's an ok product. There are cheaper brands, in fact you can get a 2 gallon kit for the price of this 1 gallon kit (if you shop around), but it does work and cure well.
