I've had a lot of trouble trying to coat a table-top with polyurethane.
I first applied regular Minwax polyurethane with a sponge brush, as the directions suggested. Inevitably I wound up with a certain amount of ugly "puddling" of the finish.
So I resanded, and used Minwax wipe-on. I put on half a dozen coats. The result: A poor finish. And even worse, it doesn't protect against water-rings when wet glasses are placed on the surface.
My question is, can I lightly sand the wipe-on finish, then put on more coats of the regular polyurethane?
I realize of course I'm likely to get "puddling" again, but I'm willing to try once more time. If it doesn't work I'll get a professional to do the refinishing, or just buy a new table.
