Polishing Compound: TechDiamondTools Diamond Lapping Paste for Professional-Grade Shine

Michael J Jarecki: I used this to polish a tungsten carbide wedding ring that had dulled to a completely matte finish over the years. The end result was a perfect mirror finish just like it was when new. It took a little practice to get the buffing technique correct using a dremel tool with a polishing wheel. With a little patience I was able to get it down. The tube has plenty of product for this application. A little bit goes a long way, though you should regularly apply small dabs while polishing to ensure the material is present and hasn't been completely wiped away by the tool. Took me about 45min of slowly working the surface of the ring with the compound, then cleaning it off, and starting over again until achieving the level of shine I wanted. Some tips: keep the dremel speed low, wear eye protection and clothing that you don't mind getting dirty as the material will spray off of the buffing wheel. It helps to apply with a finger first since the diamond paste is thick and hard to spread with the dispenser tip alone. It doesn't take much to do the job, but you don't want to let the surface being polished to get dry.

Bottom line: this product works well (provided you have the patience...

Robert D. Fish: First time using a product like this. It’s a learning curve.
Seems to be working well on high speed felt polishing pad.

The meyer family: I will pre-face this by saying I have purchased many different brands and types of diamond paste over the few weeks and almost all have the same issue with consistency and quality. The majority of the paste is as stated 200,000 grit but this is inconsistent and there are still larger chunks that will ruin a mirror finish for my purposes and for most folks purposes the pace needs to be consistent throughout and can't have random stray grits that are larger as this will always ruin mirror finish. I am using these to polish and watch parts that have to be perfect with zero scratches and even at 200,000 grit the finish should be 100% flawless but do to straight large chunks of diamond it really can't be used, maybe I just got a bad batch but this seems to be a consistent issue with almost all diamond paste products that I have used so far, however I will try to give it a go with another and see if this is better, if this turns out better I will edit this. Overall quality of this paste is great it's not died, and the quantity of diamond is exactly as stated at 50% for my per specific purchase, this really does aid and fast removal, especially as I am using this by hand and not with a...

Louise Poisson: I forgot to order ALL the different pastes so, until then, I really can't say much, aside from that it was HIGHLY recommended!

Cisco CabelloCisco Cabello: After months of trying to find a true working diamond paste, I finally decided to try TechDiamondTools. The pricing was great and quite frankly the cheap diamond paste was just not working for me (yeah...i tried to go cheap). I've been trying to find a reliable way to get scratches out of mineral glass and most internet searches claimed it was very difficult. Not only could I not find a guide to do this, but couldn't find a grit guide to use for mineral glass. The first thing I did was message the TechDiamondTools and asked for guidance. They replied to me several times and have been very courteous and helpful. They recommended several grits to try, so I went ahead and ordered.

Here is what I used, and it works GREAT! Just be patient (this is the key to perfection).
Rotary Tool (Cheap) I also used an adjustable speed control rotary tool with 3/32 pro bits compatible that is used for nail manicures. It's electric. I did a search on Amazon and the no longer sell it, but Pinkiou looks similar and it's cheap. I don't recommend using a high speed Dremel. I have one and it goes way to fast.
I started with 600, then 1,500, 3,000, and finally 5,000 grit. The results were...

Nathalie Laforest: This paste (14,000 grit) does wonder to my straight edge razor after the 10,000 grit stone (using flat leather strop).

I might still get the 50,000 grit to get a perfect edge, but it's already close to being "as new".
