I just picked up a new to me Cobra. The finish is pretty well shot and worn away. Otherwise, seems in good mechanical shape. I plan to give it a good cleaning tonight. Should I remove the side plate to clean and lube the innards? I have done that for an old S&W J frame, but is the Colt a different/more difficult revolver to open? Any caveats? I'm also considering the Gun-Kote bake on finish from Brownell's, any feedback on that product?
