Restoration of the magnesium on 1934 race car
Hello, My name is Darren and I work in an automotive restoration shop outside of Seattle, WA.I am working on a 1934 ERA race car. It is an original, unrestored vehicle.We are doing a "preservation" on it. We are trying to get an aged grey/black finish on the magnesium bits that are used all over the vehicle. Some of the motor cover plates lightened up dramaticly after cleaning. I hope someone has some experience doing this.
Any help or advice would be great. Thanks.

Probably you know that magnesium must be corrosion protected-according to one old german book you can use(1934.) boiling 70 gm potassium dichromate/20 gm copper chloride/1gm sulfuric acid/ 1 lit water solution(black finish).Try to avoid any contact with solution-use rubber rubber gloves ⇦ this on eBay or Amazon [affil links] and safety goggles ⇦ this on eBay or Amazon [affil links] !
