Touch up 870 Express Finish
I need to touch up the receiver of my 870 Express where the finish came off due to a reaction with something on a coated metal range table. The spot of bare metal is small, about 1/32" x 3/32" and many would ignore it, but I try to take care of my things. What should I use; cold-blue? It's a matte black, non-parkerized, finish.
