Dont use BLO (linseed oil) on laminates! While it won't directly dissolve the poly glues, it will form pockets between the voids in the lams, and cause problems later.
Also, any sanding you do past 320 is a waste of time and can actually glaze the wood. Finish will not stick well to glazed wood, and any film-forming finish will level 320g scratches anyway. Trust me on this.
For a semi gloss stock, I would use either A: gloss wipe-on poly(5-6 coats, lightly rubbed out with XXF steel wool between coats) Once cured you can dictate the amount of sheen you want by rubbing with a clean piece of ###F steel wool. Note, the poly will change the colour of the stock somewhat (as will any oil based finish) *Easiest*
My homade finish wich works even better is
40% Tung oil (lee valley)
40% Spar varnish (NOT urethane)
20% Turpentine
3-4 drops of Japan Drier (available at paint stores)
Wipe on a heavy coat, allow to sit for 20 minutes, buff off. Leave for 4 hours then repeat. Once you have 4-5 coats, allow to cure for 48 hours then rub-out with ###F steel wool, then apply a coat of paste wax with a soft terry cloth.
or
B: If you want the colour of the stock to stay as it is, use either laquer or water-based poly. Again, use gloss and then tone down the shine when done.
