shoe polish
x2 kiwi neutral shoe polish. Be very liberal with it and apply it all over the action it'll save you a lot of headaches if any of the bedding material over flows.
I just bedded my Weatherby Vanguarnd with Epoxy Steel and I used Mink Oil shoe polish and it worked great.
Don't know why,--always had a hard time finding Neutral shoe polish (supposed to be great for a tight fit,) --- but Liquid car wax,was easily found & worked very well.
