Hi guys. I'm curious about how long (in terms of years) Penofin retains
it's finish on hardwoods, both outdoors and indoors. I know the stuff is
pretty breathable, so I am concerned about that leaving the wood open to
more torture from mother nature. Is the UV protection just a bunch of hype?
Outdoor is always the toughest for any finish due to rain and sun.
Outdoors, I've seen Penofin stand up very well for up to five years,
sometimes only three. It depends on the exact conditions. As far as
"breathable", wood does not breath so that statement has no meaning. The UV
protection is not bad. The biggest thing Penofin has going for it is that
it is the best looking, in my opinion, oil finish for outdoor use. It does
not have an orange cast like some other brands.
I used it on a screen/storm door I made out of quarter sawn white oak a
few years ago. The door faces due South so it's about the harshest spot
it could be all year round. I used 2 coats when new and added a coat
after the first year because I could see some fading on the outside
relative to the inside. It's been 2 years since then and I'll probably
add a coat this year. I liked the results and would use it again. As I
recall, there are more than one type. I used the higher end version in
a silver can with blue decoration.

looked wonderful for about 6 months and then went away. I have had good
luck with it on a cedar shingle covered wall and it seems to hold up pretty
well on vertical surfaces. I did build an ipe work table for a friend, the
table is inside and the marine oil finish is holding up quite nicely, the
only problem is that it will still rub off on clothing a number of months
