I have an sks stock I would like to refinish in the deep red color. I have soaked it in DA to dissolve the Shellac but there seems to be some dark stains at the butt and on top of the comb. Is there a solvent that can remove this? Has anyone tried the RIT Scarlett powder mixed in poly to recreate the red finish? I've heard of people dying the stock using food color but I don't want a bright red just close to the original Russian SKS stock.
