The linseed that you get from a artist/paint/wood wooding specilaty shop is higher quality than the std Home Depot stuff,as is tung oil.
With todays new urethane/tungoil finishes, you get a more durable and water resistant finish with them than the std linseed old time finishes and you can buff them out after about 30 days curing to get a look just like hand rubbed oil finish. However,the urethanes will not be quite as hard.
I have been starting with MINwax, Helmsman spar varnish for about 4 coats to seal the pores and then start cutting it with tung oil to about 30%/70% mixture of tung to varnish.These coats I will apply and then wipe dry for maybe 15-20 coats.
Another product I like is Armor Seal by General.It is already cut with good tung oil ,but is thinner and takes more to fill the pores.
I'd stay away from std boiled linseed.I also do not tuse silica laced fillers or satin finishes.
Here is the 1936 Ithaca with the Helmsman/ tungoil finish that is awaiting buffing.
