Thanks for the suggestions on prep work but the ceiling is already
done with the T&G and the staining is already done, too. Was looking
for suggestions on a satin wood protector that might unify the finish
appearance over top of the existing stain. Stuff like Thompson's I
don't think changes the appearance, only the water resistance. We
have some test boards already done from when we were shopping for a
color we liked so we're set for that.
