Here's another method involving soaking the meteorite in a solution of sodium hydroxide, easily made from Drano. It comes via Steve Schoner. Go to: http://earthsci.org/fossils/space/craters/met/met.html and scroll down to "Repairing Meteorites". I've tried this on a number of Dronino rusters and had good success with a few of the pieces (but not one particularly stubborn one). I also regularly coat my irons with a spray from Gander Mt. outdoor stores used to protect gun metal. It's excellent and really has worked on my Campos. Unfortunately I can't remember the name of it off hand - something like Resolve or Shield. Bob
