Paint primer on old weapons?

If anyone is interested in the technical side of modern and historical conservations techniques as they pertain to ferrous products, I'd highly recommend:

An answer to M Eley, if I wanted to remove old pigments such as primers, I would begin with acetone. However, your mileage may vary. Cheers

Thanks for your response. Does acetone protect the patina? I know I can test it first, but that is a primary concern. I'll look for that reference also.

Acetone will affect certain types of patinas. Organic fats and waxes, gums, shellacs, may become dissolved. Iron chlorides may be washed away. It should not affect iron corrosion products such as goethite and akaganeite. One nice feature is it helps truly dry iron objects, where washing in distilled water can still cause flash rusting. So, it may be an option for you to consider.
