But then you would need camber to the deck, to allow excess water to flow off. Not a convenient thing on a cargo deck.

But solvent based finishes "dry". They do remain soluble in the same solvent. Like lacquers and shellac. And spray bombs of phoney "enamel".

Reactive finishes cure, like varnishes. There is an oxidative process involved. It takes time for the oxygen to react with the oils, causing the oils to cross link/polymerize. Like how the grease on your stove gets gummy? Same thing, the grease molecules hook together, becoming "plastic". Not soluble in the same solvent after curing.

Anyhow, if the intermediate coats are fully cured, then it shouldn't take any longer for the last coat to cure than any other. But I'll bet, that like me, you ain't never gonna haul nuthin on those varnished planks anyhow. A day or two will allow you to assemble the bed without too many mars.
