I tried to thin Minwax's Polyurethane with minerals spirit or paint
thinner and I get congeal mixtures???

Most of the solids are already in a lump in the bottom of the can, until
you stir them in carefully, without introducing air into the mix.

Stir completely, for about 4 minutes, before starting to thin. And don't
try to work with material that's too cold, either. Check the label, and
maybe store the cans inside?
