Hi guys

will a '31 Rad Cap respond to re-chroming? (was original chrome or nickel?) I've been offered a rather pitted example and wonder if it can be plated or if it would be better to look out for one in better condition

cheers

Hi Jules,

When it comes to chrome plating, you either pay now or pay later. In other words, you pay more for a better part or pay more for the plating of a part in poorer condition. The current method of plating parts for vintage cars is labor intensive. First, the plater removes all of the original plating by a reverse plating method. The unplated part (if a die cast pot metal part) is then examined for deteriorated metal around the pits. Using a small grinder, the deteriorated material is carefully removed. After that is completed, the part is copper plated. After the copper plating, silver colder is applied to the copper surface. The part is then hand sanded (or blocked for larger parts) to return the part to its' original shape. This may take more than one application of the copper / silver solder process. After that, copper, nickle and chrome are applied and polished between each plating. With this plating procedure, parts in poor condition can be saved. However, it will be expensive. Your radiator cap could cost over one hundred dollars to save, if it is in poor condition. The best course of action would be to get an estiamte from a shop that specializes in vintage car part plating. Stay away from shops that do production work.

Many thanks Grandpa,

you have confirmed what I was thinking. However it may be preferable to have the correct Rad Cap (albeit in poor condition) than the wrong one which we have at present!

Jules
