Educational Zone #38 - Refinishing a Sistema .45 ACP - Part 1 - Page 3
There were some badly pitted and rough spots on the pistol. I use a Very Fine wire brush to polish these parts.
Then Tman used some 180, 220, and 320 Wet-or-Dry sandpaper to polish the top of the chamber.
One advantage of the fine wire brush is that you can easily clean up checkered areas like the front of the spring cap. This one had a little rust and pitting.
Here it is after polishing.
We detail stripped the pistol and hoped that we can get it back together. This will allow me to clean and polish all the important parts and make sure there is no rust or corrosion.
