Well, last week I finally got over my fears and figured out how to detail strip my full-size USP40. I have a tutorial on polishing up the the internals to smooth out the trigger and feed ramp - I have a dremel tool with a felt tip to do the job, I just have two questions:

1) I understand you can easily bugger a gun up with a dremel in the wrong person's hands, trust me! I'm really paranoid about screwing up my pistol, as it's the only one I have and it was expensive! What speed should I use when polishing?

2) I understand that I should apply a "mild abrasive" paste to the felt tip when polishing, such as Jeweler's polish. Can anyone give advice on exactly what brand/type I should buy, and where I might be able to find it?

Any help would be much appreciated.
 
Rule of thumb

Do not use dremel to polish flat, straight, and narrow surfaces.
For trigger job go to the Shoppers Drug Mart and get nail polishing file that has 2 different grits on both sides.
Get also sand paper grits 800 & 1000. Lay it flat over the glass surface and polish flat narrow parts by dragging it over as flat as possible.
 
JB bore paste should be mild enough to just polish, myself I would use the lowest speed setting available and make an effort to do it evenly over the part, a felt tip will less the pressure and impact on a part, some people use lightly 000 or 0000 steelwool to get the rough out.

I heard people use tooth paste to polish aswell never tried it myself, Fliz is a great polish (i've use it on stubborn parts and barrels) as well but it is more aggressive the JB.

If not take it to a smith or send it to Gunnar to have them smooth it out for you. Good luck.
 
Canadian Tire has Simoniz rubbing compound in a tin. Its jeweller's rouge in a paste. Will polish metal nicely removing very little.

Flitz is only slightly more abrasive than JB, and better for smoothing out surfaces yet still providing a high polish with no (not measurable) metal removal. I use Flitz to polish reloading dies and have also used it to polish inside revolver cylinders.

At CTC you can get both rubbing compound and polishing compound. Polishing compound is a finer grit.
