[Old and Reliable]

I've used Brownell's std Acra-glas for years now- for bedding rifles to improve accuracy- and to rebild slightly damaged shotgun stocks and forearms- But- is there a method in which you can mix the resin and the hardener and some form of oil or thinner- to produce a thin skin coating to seal the exposed wood pores from the inletting/routering in the stock head areas- so that you deposit, by artist's paintbrush perhaps, a microscopic thin layer that hardens, seals the pores and any hairline interal cracks or fissures? Advise pls.
