Yes, I have used both. The urethane is great for making slugs inside of the ball. You just drill the size hole you want and fill it with the urethane mix and you now have a slug in the ball! It''s great for any size hole.
The clear epoxy is for ball plugging and works very well and takes colors well.
I also use the slugs, and they are excellent.
Get on the bandwagon with this company and buy their products!
