I posted this over in the Finishing Forum earlier today and haven't had any replies. Should have posted it here anyway, you guys are the most likely to have answers to this kind of stuff.
I put three coats of Watco on a bowl this morning (cherry). I was going to Beall buff it tonight but then the instruction label caught my eye, about applying a wipe-on finish after 72 hours if desired. Hmm. That would definitely build a finish on this piece and result in a much happier recipient!
But I need to ask first: If I use Seal-a-Cell on top of the Watco, will I still be able to Beall buff it? My instincts say it's OK but my instincts aren't always right!
