Prounol Cerium Oxide 50g – Fine Grade Glass Polishing Solution Powder – TREO 99% - 2.5 microns

This works very well on crystal with fine scratches makes a good finisher recommended

My take on the PROUNOL Cerium Oxide 50g – Fine Grade Glass Polishing Solution Powder:Pros:High Purity: With a TREO (Total Rare Earth Oxide) content of 99%, it's of high industrial standard, ensuring effective polishing.Fine Particle Size: At 2.5 microns, it's ideal for fine polishing, giving glass surfaces a perfect shine.Versatility: Suitable for various glass types, from car windows and headlights to mirrors and glass facades, making it a multi-purpose tool for glass restoration.Cost-Effective: Buying in powder form can be more economical than pre-mixed solutions, especially for frequent users.Cons:Preparation Required: You need to mix it with water at the right temperature (30°C - 50°C) for optimal performance, which takes some extra effort and time.Messy: Handling powder can be messy, and there's a risk of inhalation if not used carefully.Skill Level: Achieving the best results might require some practice, as over-polishing can potentially damage the glass.In summary, PROUNOL Cerium Oxide Powder is great for high-quality glass polishing but requires some skill and preparation for best results.

This is brilliant, if you want to remove scratches from glass it's the real deal. I also used it to remove lime scale from a glass shower door. When doing it patience is required, do not rush.

Bought this after seeing someone on youtube using it along with a dremel to get scratches out of a watch face. I tried this on my old scratched Nixon- Ticket watch face and it cracked the entire face. Could be my technique, the mixture I used or the dremel bit, so I am not blaming the powder. After going back to the video the comments repeatedly stated not to use this on watch faces as it cause too much heat. I am glad I tried it on an item I was not concerned about first.

Waste of money! I would not recommend

I had very fine but really annoying scratches on my van windscreen. I tried all sorts on home product that did not work. This stuff worked very well and that was just me with a cloth and elbow grease. So I think if you did it properly with a power tool it should work very well indeed

I've given this 2 stars as the listing photo is incredibly misleading. The photo shows a full tin, but the tin I received was virtually empty! The product weight was probably correct, and the product seemed fine, but there was only enough for one treatment. There are certainly more cost-effective products available.

Scratched a mirror during fitting. I could feel the scratch with a fingernail, so not expecting to get rid of it completely. Following the mix instructions to the letter, I had three goes. I used foam pads in an electric drill to do the rubbing, starting with a coarse pad and about 60 minutes of 'buffing'. It does appear important to keep the mix warm, I have no idea why but less effect with a cold mix.I then used the least coarse pad, similar mix and another 60 minutes. This is my process: Buff the mix over the damage. As the mix starts to dry, add more to keep the mix liquid, not dry. After three additions of mix, allow to dry and wipe off the residue. Repeat. I reckon I used about 10 mixes overall and to my amazement, it was possible to see the scratch reduce after each 3 buffings. The scratch cannot now be seen at all, and no sign of 'bloom' on the glass. Fantastic.I guess you could do the buffing by hand but I let me drill take the strain.
