Don’t use any finish on the teak (my opinion). Just scrub across the grain with salt water and a moderately soft brush. Far less work than messing around with finishes that don’t stick to teak anyway, and nothing to attract dirt like teak oils tend to do.
Yes. I like that the weather conditions don't have to be perfect, which they rarely are and a new coat can be applied every 20 to 60 plus minutes without any sanding! Allows all coats to be applied in a day in most weather.
The reason, I am told, that teak is put on boats is b/c it's a hard, durable, low maintenance wood. Yet, so many folks complain about the work of maintaining it, even to the point of avoiding buying boats that have teak. There's a disconnect here somewhere. I have teak deck--the glue-on type--along with other teak. I do with it as DougM has said. No oil or any kind of coating is applied.
But if the wood is salted by regular washing w/seawater, still not enough protection by freezing point depression? I wonder how the old timers of the wooden ships handled that problem.
