Whatever you use on the stock, try a little on your cheek before proceeding to make sure you are not allergic to it.
It is no laughing matter. A while back I tried a new kit containing little bottles of lemon and orange oil. Once dry I shouldered the stock a few times to see how it felt.
A few times were enough for an allergic reaction to start and accelerate to the point of needing hospital treatment. Feeling your tongue swell, blocking your breathign is not funny. I am not prone to allergies, this was a first, and hopefully a last time.
So it is artist grade linseed from now on, the devil I know.
