Hello, call around to all of the builders suppy stores in your area until you find a store that sells DAD's brand paint stripper, use it to strip the finish from the top of table.... then apply two coats of linseed oil and let it set for a few hours then wipe it all off
Then buy a can of clear tung oil, and wipe onto the table top with a neatly folded 'paper shop towel'.... you can renew that finish by simply wiping on another coat whenever needed, it will not accumulate. it is a self cleaning, self repairing finish.
Clear tung oil will not darken the wood any more than wetting it with water would for an example
Tung oil is applied then wiped off, it dries with a satan, not glossy finish
Tung oil is the historical standard for retaining a natural surface
Matching the surface to the rest of the table could be a problem as varnishes commonly used provide a slightly smoother, glossier surface
regarding absortion, tung oil will prevent that to the 98% but not 100% level.
Regarding tung oils self repairing nature, what happens when you apply a new coat then wipe the top layer off with a folded 'paper shop towel' is that it disolves the previous coat and any impurities, then leaves only the new oil in its place (the oil dries hard)
