I'm using Brownells epoxy to bed a grey laminate stock. Can I add somehting to get a grey tint? I can use the black thats included in the package but a lighter color would look better.

I know you already have the Brownells kit, but grey Marine-Tex will match that stock perfectly. Barring that you can get amino or aniline type dies from some art supply stores.

Ordinary RIT brand fabric dye works great. Any color imaginable.

The uncolored Probed2000 works great in grey stocks, and they have a dye kit if you want to match the McMillan colors. You can get it from Midway or directly from Score High gunsmithing.
