This is a non-toxic water repellant wod preservative developed by the
U.S. Forest Products Lab.  It is a cheap version of Thompson's
Waterseal.  I add more paraffin to soup it up.  It works very well for me
and will accept oil or latex paint if you let it fully dry.
 
3 cups polyurethane
1 oz. paraffin wax
mineral spirits to make a gallon
 
melt paraffin in double boiler or microwave.  add to other 2 ingredients
and mix well.
