I read the same post Ed,can`t see the logic in it at all,by all means wax over an oil finish if you want it a little bit shinier,I can`t remember if it said which type of sanding sealer though,if it was a Shellac one that would stick to an oil finish,but a spirit or cellulose one wouldn`t adhere properly to an oil finish and waxing after would drag it off again I would have thought,really can`t see the point of doing that.
