Thanks for sharing the pain, Kent. Misery loves company. I've never had any trouble with other WB's. Have you tried Minwax Oil Modified Poly? That stuff flows out beautifully with a cheap foam brush and gives a beautiful finish. Relatively cheap, too, only about $70/gallon. I highly recommend you try it. I guarantee success.
I'm not going to use the EnduroVar II on this project, too important to take a risk in something I don't have confidence in. But I'll get some Bubble Breaker and try it, though, in hopes I can use it for something, someday.
