Hi guys,
Just for the heck of it I am going to do a little experiment to see just how much epoxy and microballoons will hold. I mixed up a 50 50 mix of epoxy and balloons and have set a screw into 3/8" deep layer of it.
Tomorrow when it sets up I will use a luggage scale to see what the yield point is. When I made the mixture any thicker it would be a pain to get it to flow into the cavity. I like the G2 epoxy it seems to have a pot life of hours, great for this type of project, as long as it is strong enough
