Sikken Cetol is awesome, it is the best outdoor finish I’ve ever used, but yes, it is expensive $125 for a gallon. It is pretty thick and has very strict instructions that require you to put 3 and only 3 coats on, 24h apart. It also has a distinct orange-yellow tinge to it…I wouldn’t use it for everything, but for durability I’m not sure it can be beat!
