I disagree. The amount of fiberglass + epoxy I used weighed less than 1/8 one ounce. I used a very small amount of expoxy with about a 1/2 inch square piece of .50 oz cloth. Before I did this, I could easily break the expoxied joint with my hands, now I'd have to apply at least twice the force. Why risk it for 1/8 of an ounce? Once you sand it down it's nearly flush with the surface. It didn't interfere at all with my formers.

Enjoy and keep up the posting!
