Ok, I’ve decided to brown the lock on my Woodsrunner. I’ve got the lock disassembled and I’m ready to sand. I’ve started sanding the mill marks off the lock plate. Should I try to sand the roughness from the cock or brown is as it is. I plan to brown the plate, cock and back of the frizzen. I used the Laurel Mountain product on barrels but never a lock. Any suggestions?? Thx, E..
