I need to know if anyone making brass bullet casing pens can advise me on the use of the spray brass lacquer i bought at the woodcraft store. A salesman there told me he had used it on his antique rifle brass and has had No tarnishing in a "few" years. Then I got home and read the article in woodturning design magazine and it said somethng to the effect of "don't waste your money on brass lacquer because it just wears off anyway". I'm looking for some people with real experince using it on brass casing pens to help me out here. Thanks for any suggestions!
