I used this finishing oil on a outside maple bar top. It was entirely exposed to the sun and elements. It says in the instructions that it's meant for vertical surfaces. I used it on the vertical parts and the horizontal (flat) surfaces. It worked perfect on the vertical surfaces and after a year it still looks good. The horizontal parts did indeed weather and the finish didn't last on the horizontal areas. I'll have to try something else for those surfaces. Overall the product did what it said it can do and the instructions pre-warned me to know what to expect. My experimentation continues!
