I'm not up on tung oil ,
but of pure raw linseed oil it is said
"One coat a day for a week, one coat a week for a month and one coat of month for a year."

I wouldn't use raw linseed oil on any woodwork. BTW, that saying is one of those propagated sayings started on forums, and repeated ad nauseum. Actually it was meant to apply to mineral oil maintenance for butcher block. But, as any oil treatments, it should be applied as needed.

That will come as a bit of a surprise to the generations of furniture makers who have used linseed oil over the centuries .

Petroleum derived mineral oil being 19th -20th century product
