Deck oiling
I planned leaving deck planks oiled only with Owatrol D1. It gives satin finish, should not be slippery when wet and should protect the wood from water and stains. Well, maybe I did something wrong or pine is not suitable for D1 (it is, of course) but it did not work as intended: dirt from boots was staining wood and was hard to remove.
I decided to run the complete system and coat the deck with D2. It behaves like a varnish, leaving glossy surface. Applying several coats should protect the wood properly and be much easier to maintain than varnish.
I used it when I renovated Glypto and was impressed by ease of use and varnish-like finish, without a need to be in a hurry to maintain wet edge.
To prevent it from being ice-like slippery when wet I will add some anti-slip pearls on last application.
Mast and yard got the second coat of varnish. And small flies.
Whenever I do this I can bet that these buggers pop-up from nowhere and stick to fresh varnish.
