I really like Vermont Natural Coatings Polywhey varnish. But the solids settle badly and I always have to stir the stuff.
I don't want to buy one of those paint shakers. What I want to do is gently roll the can. VNC uses all plastic containers that shouldn't leak. My thought is a very short piece of 6" pvc pipe with a cap at each end. I mount it between centers and run it for a couple of hours at very slow speed.
I live near a good plumbing supply (Ferguson) so the caps aren't a problem. Where could I find an 8" piece of 6" pvc?
