I'm all done !
My 7 mag turned out ok....
A few little bumps in the flutes, I think from small pieces of trimmed coating ?
Bolt came out ok. Will let dry, tape off the the ending edges of the flutes, and make the flutes blend into the bolt body coating.
Receiver, bottom metal, and trigger, all came out beautiful.
I also did the same stainless barrel, except in 30-06. Did just the flutes.
Taped off 1 valley at a time, let dry a bit, removed tape, and cleaned up the top edges with a razor blade.
Pics later...
