1) I noted where all the finish had been worn which indicated points of contact/friction between moving parts
2) Starting on these points I started by hand polishing using Flitz (sold for polishing and protecting real steel but still safe on plastics and provides corrosion protection). There was an improvement in the "feel" of the surface polished, i.e. it felt smoother. However, the hand polishing was pretty laborious and wasn't smoothing out some of the imperfections I was coming across on the inside of the slide so I decided to break out my trusty Dremel with felt polishing tip.
WARNING - SEE RULES REGARDING UPGRADES AND MODIFICATIONS IN SUBFORUM OF SAME NAME- USE A DREMEL AT YOUR OWN RISK
3) I proceeded to polish with the dremel and Flitz all interior surfaces of the slide I could reasonably get to. A couple places I had to swith to a 320 grit finish plastic wheel where I needed a little more removed and then finished with felt with Flitz.
Now, although I wouldn't call the finish of the slide rough to begin with, it wasn't by any means smooth, this became extremely evident as I completed the first area and compared it to the original finish.
4) I also polished all of the areas of the frame that makes physical contact with the slide.
Sorry, family just got home, time to serve up dinner, I'll come back and edit post later...
so how did everything work out?
