The supply houses used to sell a version. I use a real unadulterated resin that is the base for varnish. Thinned with Xylene (nasty stuff). I think all of them are some type of varnish and I'm not sure how critical it is just which one. I think the real benefit is the lubrication it provides (rather than any sealing or wood treatment properties) so that the pin gets driven in doing the least amount of damage to the surface of the wood as it goes down. Since the inside of the hole is basically all end grain, the PDF is readily absorbed and probably doesn't leave much residue on the surface of the block. At least that's my theory.
