Quoted: How was the polishing on the flats done?
I bought a SS Springfield Armory 1911, and I was wondering what the steps you took were.
Thanks.

Let me warn you, a finish like this shows scratches. Most stainless guns have a brushed finish on the flats, bead blasted on the rounds. Whenever your pistol goes into a holster or is handled with gloves or dirty hands, you're probably putting extremely small scratches in the finish. However, the brushed finish is actually more coarse than the small scratches guns get everyday, even if you can see your reflection in the slide. Due to the "coarseness" of factory finishes, you don't see the small scratches. With a polish at this level, you will be constantly having to polish out small scratches.
Here's what was done. You need a sanding block, which you can get at any hardware or home improvement store. You will also need a small supply of sanding paper. You need to start with 400 or 600 grit, depending on how rough the machining is underneath. You will need to go progressively finer, so you'll need 1000, 1200, 1500, and 2000 grit sandpaper, which you can get at automotive paint shops. Finally, you'll need the proper polish, and the ability to remove the grip screw bushings from the frame.
The grip screw bushings are staked in on Springfields. To remove them, you can use a screwdriver if you're careful enough to keep the balde perfectly square to the bushing, but that's very hard to do. Even so, it's highly possible that you will ruin the bushings. You might as well just order new ones. There are dedicated bushing bits, but you will still probably ruin the bushings. Also, after you reinstall the bushings, you should at the very least loctite them, though I re-stake them.
As for polish, here's the secret on this gun. My neighbor used to have show bikes, with lots of polished billet, chrome, etc. He used a product called Wenol. I had used Simichrome, Flitz, and about a half dozen less known products, and until Wenol, Simichrome was the best for this type of finish. Wenol is even better. It comes in two grades in the U.S., red and blue. Once you get the block sanding done, take some red Wenol and put it on the 2000 grit sandpaper. This will bring out a high polish. After that, use a soft non synthetic cloth with red Wenol, then blue. Be careful not to hit the rounds. That's it. It takes around 40 hours of sanding/polishing to get to this level, if I had to take a guess.
