Thanks Victor! Your adventure prompted us to call the folks at the Flecto Company in Oakland, a leading manufacturer of clear wood finishing products.
Our concern was relative to any potential problems or health hazards that may be attached to the technique that you are suggesting. And, as a result we have some good news for you. The Flecto Company applauds your efforts and is especially pleased that you opted to use three complete coats. They say that this will significantly improve the longevity of the finish and will provide you with a surface that is not only impervious to liquids, but will stand up to the kind of abuse that kitchen cabinet shelves and drawers are likely to sustain.
One Caution: Allow the final coat to air dry at least 72 hours or until most of the unpleasant odor associated with the use of this type of product has dissipated.
P.S. We guess that shelf paper will not be among the most wanted items on your Christmas list this year!
