I have said it several times before that I won't make anything out of MDF. I am talking about small projects like clocks and a Santa and his sleigh. If you don't seal it really well painting is a nightmare. Try these guys for some very good scroll wood. Several guys on this forum recommended them and now I do to. Now to your question. I don't have a clue on how to answer it but others will. Now ain't that a bummer.
