Wanted to post my experience with Bristol finish. I applied several coats, and then carefully stored the remainder of the unmixed product as directed for a few months, and to my dismay, the catalyst had hardened and was ruined. Since I did exactly what I was supposed to, I contacted the manufacturer, as I had lost a significant quantity. They would NOT stand behind their product, and credit me for the additional catalyst, that I now have to purchase.
The jury is still out on how the finish itself performs, but it really needs to deliver, after this setback, in order to earn my recommendation.
