Hello

Have been looking at some old stanley 45 planes. The bead and combination plane. Like  the different profiles and diversity of this tool. Also wonder why Lee Valley never made profiled cutters for their plow plane (I have and adore it)?  Anyhow the stanley I believe has a nickel finish to it. Most, not all, I have seen have some degree of rust to them. Will the products available today, evaporust or naval jelly, remove the rust and the finish as well or just the rust? Don’t mind a little rust however would like safe option to restore them if possible. I’m looking for a user, not a collectible. From what I have seen rust free 45’s can come with a pretty hefty price tag? Any thoughts or advice would be appreciated?

Thanks
