Charles and David,

Sanding does not remove blush, it just spreads it around. Blush is a wax like substance, try sanding a lot of wax off of a piece of wood, it heats up nicely, melts, and colls and hardens somewhere else. After the kayak has been sanded, wash it down with a mild soap and water. Rinse it thoroughly. Wipe with a clean towel (without fabric softener). Apply the varnish. If you have been out paddling the kayak while waiting to varnish it, the blush is probably gone, but washing before varvishing will help make sure you dont have any contaminants on the surface. My first varnishing experience was awful, I always wash before varnishing now.
