Would this work well for an iphone with light scratches on a small corner of the screen? iPhone 11 Pro

Hi, for light scratches, use a kit of 2k+4k+8k+50k (or just 4k+8k+50k for very light scratches) Grit pastes. For deep scratches, trying to remove them is not screen functionality safe. However, the same kit will help to make those scratches less noticeable.

What kind of oil do you use? Can I use this on a leather strop?

We use oleic acid. But if you need to loosen the compound up, you can add practically any machine or motor oil to it. Yes, it can be used both on leather strop/cloth and on wool cloth.

What is the significance of the concentration? Wouldn't the grit be the same regardless of how much powder is in the compound?

From my understanding, it would be like 100 grit sandpaper with only part of the sand on it. Yes, it's still 100 grit, but there isn't as many granules of sand, which would make you use more and it would take longer. This paste worked extremely well on polishing my tungsten carbide ring.

how would you load a leather stope with this?

I'm not sure if I'll get this right, but I'd dispense a fair amount onto the strop and rub it in evenly. This is an oil paste , so you should get an even coating.

Awesome polishing compound!!!!!

This stuff worked perfectly for polishing my bullet press in my redding bullet seating die, the die was grabbing or holding the bullets after being pressed in so I put some of this polishing compound on a bullet tip and used my drill for about 15 minutes and it was a mirror finish in side it worked perfectly.

Great paste to maintain straight razors.

I got this to keep my Thiers Issard razor in top form. It's excellent. All I do is strop the razor a handful of passes on a strop pasted with this & it has given a very sharp but gentle edge to a razor that previously needed to get back onto the stones after a few shaves. I highly recommend this . It's a top quality paste from a great seller. 10out of 10
