And a quick reminder. One coat of the rust brown solution will not get the job done. It takes several. Once you have the parts degreased, learn to love latex gloves, don't go near the parts without them on. I am not sure if John F is making Ol' Thunder Cold Brown or not, but if he is, that is the best I have found. I guess Laurel Mountain is next best. I saw where October Country is making a cold brown, probably a copy cat version of Ol' Thunder, no idea if it works well or not. Once you are happy with the look, be sure to kill the browning solution. I used washing soda (I think it is called), then apply a liberal dose of something oily. Personally, I do like October Country's Bumblin' Bear Grease for metal treatment, a wood preservative and on leather as well. Good stuff.
