Polyurethane bubbles driving me crazy
I am going crazy trying to "finish" a project. I am getting bubbles in my oil based polyurethane, and I don't know why. I've watched hours of videos on U-tube, read countless articles, tried many techniques, but am still getting bubbles. No, I'm not shaking the can, and I did buy a good brush, and I am applying slowly and not brushing vigorously. My first few coats were full strength poly, and I think I was sanding too much in between coats, so I tried sanding lighter, then i diluted poly with some paint thinner. This went on much easier, and even though I saw thousands of bubbles at application, I was hoping most would pop during drying because of the thinned solution. The next morning, the bubbles were bad, and kind of streaky (see picture) If anybody has any suggestions, it would be greatly enormously appreciated. Thank you.
