Here are some pics of my failed, or rather unfinished project.
It was an almost like new gun when I got it, however the wood was kind of dirty/stained.
The idea was to bring back the original light color of the beech wood and then cover it with some kind of protective coat.
So I sanded it carefully down (240/400grid), and then tried to find the only coat I could which has following properties :
a: non synthetic, b: doesn't change the color of the wood, and c: has flat finish
I went with
Auro 518 which worked well in so far, as there was almost no change of color observable.
Downside: Even after 2 months of drying time, the surface still had this slightly tacky haptic.
This was unacceptable as I feared it could attract all kinds of dirt to the now clean and bright wood.
Removed all the tacky stuff with orange oil and decided to leave it that.
(Gun will probably be sold anyways since this is my 5th FEG and 6th UF)
