I have been using Penofin for years and like it. Its a Brazilian rosewood oil. Go to
http://www.penofin.com/ and read up. I use the exotic hardwood oil. From what I was told the only difference between this one and the marine is viscosityand $10
If you do use it it does smell odd ffor a little while and you MUST wipe it off as per the directions.
Good luck
Chris
ps I use it on other wood too.......
