Hi Count, I will do this tomorrow and post the results.
I couldn't find your picture of the day you mentioned but do you mean this one? http://www.encyclopedia-of-meteorites.com/test/52752_5909.jpg Thanks for the advice.

The greyish brown color is probably as close as your going to get after laying a little "gold" on the rock. If your just wanting to make it look nice and not going to study it, I would immerse this stone meteorite in 90% alcohol for ten minutes and then bake it dry at 325 degrees for about ten minutes. Polish it off with a micro-fiber cloth. A greyish brown, with patches of darker fusion crust, in a weathered chondrite is pretty close to normal. Especially after it has terrestialized to the point of the partial, or complete, dissapearance of visible fusion crust. Although meteorites can sure vary according to their origin, cosmic and terrestial life. If you keep the recent "Meteorite of the Day" pics of a couple of days ago, look at my Stump Spring LL6 weathered chondrite which was treated as described above. Washed with distilled water. Dryed. Stainless dremel to remove terrestial caliche, etc. and then alcohol soak and drying. Then polished with micro-fiber cloth.
