Photos of tung oil on outside stools The one on the left was coated in 2020, the one on the right in 2021. The orange tinting comes from the zinc which is added to Tung oil to make "Outdoor defense oil" I believe these both had 2 initial coats of outdoor defense oil, then a few follow-up coats of pure Tung oil. Despite being outside in coastal florida all day long (not always in direct sun like the photo) and rode out the abrasive effects of 2 major hurricanes, the are doing remarkably well. They were kind of a test, and so far I am pretty pleased with the results.
