Yes, I have used Envirotex Lite to make "mycarta" out of lenin fabric and I am now using it to make canvas "mycarta". you have to clamp it very tight or it tends to de-laminate.
I also have coated a silk wrap tanto handle. I may have used to much, the cord wrapping became very hard. also it has a very fast reaction time. when you mix the two parts together you have to work fast or it will gell . I hope this helps you.
