The Sonotube Fiberglassing Project

I sanded exterior and interior with #80 sandpaper last night; I just finished applying a coat of fiberglass resin to the inside and ends of the tube.  The Sonotube absorbed the epoxy in a manner that can only be called greedy, especially on the ends, where there was no wax to discourage it.  I decided to just apply epoxy; the fiberglass cloth would make it stronger, but it is actually plenty strong as is; it just needed a bit more stiffness, and the resin should do that just fine.

Now I need to treadmill while I give it a few hours to harden.  It is obviously a bit big to pop in the oven.
