I made the mistake of trying to polish an older blued revolver with Flitz and it promptly removed about 20%of the finish. Has anyone else had this issue? Or was I hoodwinked and someone had put some kind of "cover blue" on this old Smith?
I'd be willing to bet that someone put something on it. I bought a Colt Trooper once that looked like it had blotchy fingerprints all over it. I took it home and used Flitz on it and some ugly black gook just peeled off it. Under that was a worn, but still nice looking blue. I'm guessing it had been cold blued at some point.
On the other hand I use it on almost all my revolvers and have never seen any indication that it takes off the blue. You're trying to polish something, not sandpaper it. Work gently. By hand.
I have this Model 19 I bought a year or so ago. It was ROUGH when I got it.
I Flitzed it a few times, then waxed it with Meguir's car wax, and it looks like this now.
Did it take off some of the blueing? Maybe, but it took off a lot of "gunk" too and the gun looks 100% better. The edges where the blue was worn down to bare metal are blended and smoothed out. There was a lot of fine, almost microscopic rust on it apparently. All that is gone and the finish is smooth to the touch.
I bought this Model 58 a few weeks ago.
Doesn't look bad, but I lightly Flitzed it, waxed it, and changed the grips.
I freely admit the light is different, but I can see no damage to the finish. I'm sure if you buff hard enough, you can do damage, but just work gently.
