Diamond Polishing Paste Kit — 3 Grits (500, 800, 1200) | USA Made | Oil-Based Syringes | Progressive Polishing Set for Metal, Glass, Gemstone, Knife, Jewelry | 50% Diamond Powder

Applicator syringe works well for fitting paste into narrow places, grits seemed about right in terms of effectiveness, and I liked having a few different ones included for final polishing

this product was recommended by my Unkle, (retired Special Forces sniper, and civil service SF sniper instructor). used as he directed for a great result.

I did use it to get a better sliding tolerance between two concentric metallic components of a precision comparator. Once the movement was smooth enough, then it was removed using a fast drying solvent to flush it out. The syringe applicator was instrumental to use it in tight spaces.

They are just what I needed
