Sorry, I know, another dining-room-table-finishing post... My question is how to best apply Behlen Rockhard tabletop varnish without leaving bubbles. Background: brand new table had some very thin coat of finish on top, over an oak veneer, which I dry-sanded with 320 grit then wiped with a tack cloth. I bought what I thought was a nice brush (china white bristle for stain/varnish), didn't shake the can, and brushed on the varnish slowly, and I still got quite a few bubbles. Most of them "settled" out and disappeared as the coat of varnish kind of spread out/flowed on the table, but several are still there. It was fairly humid, which I thought would be good to prolong drying time and allow more bubbles to pop without leaving a mark. I plan to let this dry several days, dry sand again with 320, and then add a second coat of Rockhard. Would thinning with mineral spirits help reduce bubbles on the next coat? If so, would 10-25% min spirits make a difference, or should I go for 50%? Should I apply this with a rag, thinned or unthinned? Finally, what difference does it make to wet-sand, and does that involve water or mineral spirits? Does wet-sanding help at all between coats, or only at the end? Thanks very much for your advice and opinions, Andy
