Welcome to the Files!

I wouldn't paint that stock, personally. I don't know the Canadian market but I'm with pcke. An Izhevsk stock, even sanded and stripped of shellac like yours, is worth keeping in its current form where it can still be partially restored. Maybe the "Thai Seedlac" https://www.shellac.net/Shellac_ordering_list.html

Welcome aboard from Washington State

From what I understand, Russia used garnet shellac.

Kingfisher welcome from Florida, I too hope you do not paint that stock!

Ok thank you all.. And won't bother painting the work if its a bad idea.. If it's a refurbished with that stock .. What is an average price in the US market?

From what I understand, Russia used garnet shellac.

Did they also use some form of wood preservative such as pine tar or creosote under the garnet shellac?  This type of processing may account for those uber dark red SKSs.

Who knows...   I have however read where people do believe they used pine tar.    Interesting observation montigre!
