I looked through that link.
Personally, I don't think that bedding an action by just filling in areas where there isn't contact is the correct method.
This results in areas of very thin epoxy (which is likely to crack out over time), or none at all where he has firm contact of wood/metal.
I believe wood needs to be removed in all areas to get as even a layer of epoxy as possible throughout, not just the "voids". The divots are fine and will help in those thin areas, but best to remove some wood instead. If it's applied to minimum recommended thickness, you'll get a sufficient chemical bond to the wood. When I bed polymer stocks, drilling out divots and roughing the surface is required because you won't get the same chemical bond.
