Chemical Strawing acid

I am interested in trying the chemical strawing on a 1916 DWM shooter, matching numbers but heavily polished and reblued, including the originally strawed parts. I think a surface chemical treatment reduces the risk of harming these old parts, especially the ejector, with heating by a novice. Also, I believe the chemical coloring is more durable.

No on both. If you heat it to the correct color, you have heated to the same temperature the factory used. In other words: The temper won't be affected. The chemical bluing will be of the same quality as a very thin cold blue, ie. not very durable at all.
