I picked up a can of Deft sanding sealer and didn't read it until I got it
home. By the sounds of this stuff it's a laquer base so that would make it
incompatible with MinWax polyurethane, right?




Lacquer based sanding sealers work fine UNDER most varnishes, including
polyurethane. The sealer will dry extremely fast, allowing you to
finish the sanding / sealing stages quickly.

You just don't want to use a lacquer product OVER a varnish.

Dewaxed shellac, such as Seal Coat, or shop-mixed stuff also makes an
excellent sanding sealer. Seal Coat is a universal sealer and barrier,
and is excellent to keep on hand.
