   If the surface is smooth enough as it is I would think just giving it a good cleaning and maybe a scuff with sandpaper will be enough.  I don't think there is any adhesion problems with paint and therefore no need for another coat of anything.

   Alan - I like to use a pigmented shellac, like Zinsser BIN before painting. The shellac component gives it a good bond to the surface and seals any potential problems and the pigment provides a uniform white base for the paint. It sands smooth and level really well so the paint job looks good.

   I mix my own shellac.  I have a number of shellac suitable syes, but all are in the wood tones.  What would I use for a white dye?  Thanks.

   It would be easier to just buy some KILZ probably--it is white pigmented shellac.Gretchen

   Thanks.  Actually, we may have some in the basement.  I did not realize this was a shellac product.  So much to learn, so little time; Coffee!

   Make sure it isn't too old--that it will dry. Try a sample board. No point in putting a sticky mess on top of this!!Gretchen

   The white pigment isn't a requirement - it just helps give you a white base for the paint (and the pre-mixed primer sands so easy it's not a chore at all). If you wanted to, you could add a little white pigment to the shellac you mix, but it doesn't seem worth the effort & expense.

   Check the "Kilz" you have on hand to make sure it's shellac based - some primers are water-base, some oil-base, some shellac. Shellac is the best barrier coat (besides vinyl sealer).

   Dewaxed shellac is only important if you are going to use either an oil based or waterborne POLY varnish. If you are painting, then any shellac is fine. Your plan is just fine.
