Thanks for your response, Bill. I went to Home Depot but they didn't have anything that was oil based, so I finally used the water based sealer I had. It worked, but raised the grain a lot, leaving me with a whole lot of sanding to do in tiny places, etc. Won't do that again!
I've never used shellac as you suggested, and not sure what I should look for when I visit the paint departments again. Could you be a bit more specific on what I should look for? I know, most everyone else knows the answer to that, but I'm still a relative "newby' and feeling my way.
Thanks again,
John
