Meguiar’s Mirror Glaze M105 Ultra-Cut Compound, Rubbing Compound for Car Scratches and Heavy Swirls, While Adding Shine on Your Car, Safe and Effective on Paint and Clear Coats, 8 Oz

This product will work best in scratches that have peeled the first layer -clear coating- of your vehicle’s paint. As the bottle states, it removes 1,200 grit or finer sanding marks.If you want to find out if the ultra-cut compound would work for you before purchasing it, you will need to get the scratch wet with soapy water using an atomizer or spray. If the scratch disappears when wet, then you will be able to buff it out with this product. For context, the scratch in my vehicle was about 5 inches long, and 80% percent of it disappeared when wet, with the exception of the deepest areas at the beginning and end of the scratch. Because of this, I was far from certain that the product would work, but it did!Here are the steps that you need to follow:1) Using an atomizer/spray, clean the area with soapy water using a microfiber rag.2) Once dry, proceed to apply the product along the scratch.3) If buffing by hand, alternate in between circular and perpendicular movements in relation to the scratch. For instance, do three rounds of circular motion, then three round of perpendicular motion and so on. Add product as needed. Don’t be stingy with it. I used about a quarter of the bottle to get rid of the scratch.4) You will need to be patient. Within the first 5 to 10 minutes you might see little to no change. After about 10 minutes you will see that the scratch starts to disappear. In my case, the scratch was visually gone, but at an angle I could still see its indentation. Up to that point I thought the product was merely masking the scratch. However, after 30 minutes of buffing, the scratch was totally gone! In total, I spent about 30 to 40 minutes to get rid of a 5 inch scratch. I’m certain that the process would had been much faster if I had used a rotary buffer or DA polisher.Lastly, I tried the ultra-cut compound in other minor/more superficial scratches, and needless to say I spent much less time -10 to 15 minutes- in each of those.

I'm not a pro by any definition but have done a fair amount of body/paint and have detailed for years. I was struggling with the M100, which I bought in a pinch. The 100 has a very, very short work time and if it dries or you dry it while buffing you have to use a detail spray or similar to remove. Not a fan at all. I had used this M105 a couple of years back on a repaint of a fiberglass trike body and it did a great job. I installed rockers and a couple of patch panels on an older Ford Econoline and did a rattle can paint and clear blend. In using the Spraymax spot blender I always seem to get some grain/dry spray. After a wet sand of those areas using 1200, 2k, 3k and 5000 sandpaper I used the M105 with an 1 1/4" knap wool pad on a rotary at low speed, not too much product and a light touch helps to prevent buffer drying on the panel and as expected brought out a beautiful mirror shine on those areas. I had previously used Maguires Ultimate Compound and polish on the other body areas just to brighten the finish. White paint is a bit more forgiving of swirl and scratches but after seeing the 105 next to it I'm going to have to go over it all again. The deepness of the reflections is night and day. The Ultimate polish used with a D/A and polishing pad seems to work just fine with this. 105 has a long work window and removal is easy and painless. I'll stick with this going forward. I'm sure most of my paint issues are self-inflicted but most learning curves are. Keep in mind this is an 8 oz. bottle but it was a perfect size for my needs. Hope this saves somebody some M100 grief.

got it time.. unfortunately unable to try it yet, will update lattter

I have a 2022 Graber Blue Mustang that I bought in October 2023 with only 2500 miles. I show the car in car shows and have been using Groits Ceramic Quick Detailer before the shows and it has looked pretty good, but you can still see some of the fine scratches and swirls. So, I decided to give this a try. I followed the directions and applied a small 5x5 section at a time. Then used a small Ryobi Orbital polisher. Then wiped the area clean by hand to finish. You had to work quickly to make sure not to let the polish dry. The results were amazing. It left absolutely no scratches or swirls and the gloss was like a mirror. It looked like I had worked for days. I would highly recommend.

I do not know how this product is supposed to be used, but I needed an ultra fine abrasive to produce a chrome like shine to stainless steel. After a 2500 grit sandpaper rub, this polish really made it shine!! Removed the fine lines of the sandpaper and made it glow. Move product out of automotive and add it to metal fabrication. Great usability!!

I used Meguiar's Mirror Glaze Ultra-Cut Compound on my car to remove some deep scratches, and I’m amazed at the results! This product is incredibly effective — it cut through the imperfections and left the paint looking smooth and glossy again. The formula is powerful enough to remove scratches but gentle enough to avoid damaging the paint. It restored the shine beautifully, and the car looks like it’s just been detailed. The 32 fl oz bottle is a great size, providing enough product for multiple uses. If you're looking to restore your car’s finish and eliminate imperfections, this compound is a must-have!

This stuff is really amazing. It goes on light and easy, and with a white pad it leaves no swirls. Doesn’t take much effort to wipe off after polishing complete and leaves a very clean and shiny surface. I seek this out over all other finish-polishes.

I bought for mirror scratches didn’t work but good for paint scratches not for mirrors
