Most people work with fiberglass matt for small projects because it is very cheap. However, I find using fiberglass cloth is much easier as we are working with a small diameter curve and cloth is more flexible. Cloth also gives a smoother finish.

Buy Cloth tape 10-12 inches wide by 2 yards long. Cut up the cloth to wrap the tube with 2-3 layers.

I had a choice between polyester resin and epoxy resin. I went with general purpose epoxy as it has no odor and does not shrink as it cures.
