Professional M105 Ultra Cut Compound, 8oz

I purchased this after reading rave reviews in several different forums and websites. The reviewers were right. This product does exactly what it is intended to do. It's perfect for compounding a vehicle in need of paint correction. If you have swirls and light scratches, then this is what you use if you want to eliminate them. For those that use off the shelf waxes at the auto store (as I used to do), they only temporarily cover up the swirls, they do not remove them. I spent close to 30 hours researching how to properly do paint correction and this was one of the most hyped compounding polishes out there from the pros. I started by using a clay bar and clay lubricant on my car to remove the contaminants in the clear coat that even the M105 won't pull out. Then after washing the car, I used a Porter Cable DA polisher (also purchased here on Amazon) to compound the car's surface with the appropriate pad (typically orange). I worked in 2 foot by 2 foot sections and used cross hatch patterns to assure even coverage. This really brought out a lot of shine and this isn't even the polishing stage yet! It wouldn't pull out one heavier scratch that I have, but it made quick work of the smaller scratches and completely removed the swirl marks. Keep in mind that this is an abrasive. You don't want to use this every time you detail your car because it removes a very small amount of the clear coat. You should hopefully only have to use this once to correct the issues then you can maintain the paint from there. I then used Meguiar's M205 to polish the car, again using the DA but this time with a white pad designed for polishing This is what brings out the shine! It's like wood working.. you start with a rougher 120 grit to get the majority of the roughness out, then move up to a less aggressive 240 grit sandpaper to smooth it out even more. These products are simply liquid sandpaper - one has more grit and the other has less. One does the dirty work, the other finishes it off For what it's worth, I then followed up the polishing with 2 coats of sealant and 2 coats of Carnuba wax. The before and after is simply amazing and that's saying a lot because the car I did all of this on is yellow, not a color known for high gloss and reflection quality like you see on darker cars Highly recommended!

This stuff is magic. My son, the day before his 16th birthday, swiped my garage and left a beautiful white tattoo of paint/scratches on the side board. After some muscle grease and leveraging a drill/buffing sponge, the paint/scratches are all gone. Like, gone gone. I would never have thought it would work this well. Amazing!! I don't typically write reviews, so I don't have a before and after picture, but trust me when I say this stuff works phenomenally!

Good stuff, but works best on only very minor abrasions

I used a small amount with an applicator pad on one section at a time, then wiped it off with a microfiber towel. It took some rubbing, so I worked slowly and checked the spot between passes instead of going at the whole hood at once. The marks looked less noticeable afterward, and the paint had a nicer shine in the afternoon sun. I was glad I tried it when my roommate pointed out the improvement while we were loading groceries into the trunk.

I run a small detail corner inside my auto repair shop, so i grabbed this for fixing customer complaints about haze after buffing. First week, a guy brought in a black SUV with nasty dealership swirls on the hood. I used M105 on a microfiber cutting pad with my DA polisher at speed 4, two slow passes, and the grayish haze just cleared up fast. I like that it cuts strong but still wipes off clean, which keeps my front desk from filling up with people waiting. Followed it with a lighter polish and the hood looked nice under the shop LEDs. This stuff saves me time between jobs.

I tried a small amount on one section with a polishing pad, working slowly and checking the paint between passes. It cut through the dull marks and left the area looking clearer. I followed with polish and wax, since this is a cutting compound, not a one-step shine product. I didn’t need much pressure, just patience and a clean pad. A little went a long way for the spots I worked on, so the 8-ounce bottle should last me a while.

I used this with a large orbital machine and a foam bonnet. I was starting with a surface that had been sanded with 1500, 2000, and 2500. Since the product advertises quick removal of 1200 grit marks, I figured I was safe using 1500 and that it would go quick since I finished sanding with 2500. I primed the foam with Final Inspection. This tip is found on the bottle of 205, but I used it with 105 too. On the first panel I found that the 105 quickly polished the fine haze left by the 2500, but that it left a lot of deeper scratches. That may be in part due to the poor performance of my orbital machine (a Craftsman). I'm sure I would have seen better results from a rotary wheel, but I choose 105 over the traditional Heavy Cut and Medium Cut Cleaners because I don't have a rotary and all the wheels. With some more work, the 105 removed all the sanding marks, but I found that it dried fairly quickly (working in the shade on cool panels) and I ended up using a lot of it. I ended up using 8 oz on one medium-sized SUV (and I didn't even do the roof or hood since those have a different finish). It was important to follow directions and wipe the compound off each panel as I finished. I found that as I reduced the pressure on my orbital, the foam pad would buff most of the compound off as it dried up within a minute or so. I wiped the rest off with microfiber. I can imagine if someone put this all over the entire car in the sun, they'd have one heck of a job getting it off. I figure the difference between Professional products and the consumer ones, is that with the professional ones, it really is critical that you follow directions. When I was done, the surface was ready for 205. Really, my only misgiving about it is it could have been coarser. If I were to do this job again, I would want to have started with 800 grit, and finished with 1200 or 1500, but this 105 compound would not have handled those sanding marks, at least not without a wheel. Going to a more aggressive abrasive means adding more steps to the finished work, and from my initial experience, this product doesn't fit in the series of steps in a place to be as useful as it could be. I can almost do the same job with Fine Cut Cleaner (traditional diminishing abrasives). I also used 205, which I found much easier to use as it did not dry so fast. I could do larger areas at a time and it was just much easier to use. But it left a lot of very fine swirl marks that Show Car Glaze took off. I probably could have skipped 205 and just used No. 7.

The product is very good. I have been using this for years ir brand. I didn’t look too well on the label. It was a very little bottle. When I looked in the picture it’s looked like it’s should be much bigger. Of course I should have looked better in the label. I think this is a way too let customer think it’s bigger. It’s not a good behavior. I would buy this from Amazon anymore. Another thing is that every thing comes to late. I have asked some people to come over and do the work for me. They show up at 6 am because of the heat. I was not able to reach out to them yesterday.

Removed scratches from my guitar effectively, don’t leave any powder or residuals.

Compré un auto del 2013 que tenía varios rayones y muchísima oxidación. Inicialmente intenté con el ultimate polish de la misma marca, y no funcionó. Me puse a estudiar y vi que para corregir se debe usar este producto primero, así que lo compré. El resultado fue mágico. Intenté subir fotos del antes y el después, pero no fue posible. Así que sólo puedo decir que es impresionante. Por los rayones no hizo gran cosa, aunque sí se ven menos. Pero su efecto sobre las manchas de oxidación fue increíble, pues las quitó completamente y ahora la pintura se ve como nueva. Después le di una pasada con el ultimate polish y terminé con cera de caranuba. Todo lo hice con un kit para poner los bonetes en un taladro, así es que ni siquiera necesitas el gran equipo para ocuparla. Yo estaba pensando en mandar a repintar el auto completo, pero ahora creo que solamente repintaré las facias, pues el dueño anterior si le dió varios golpes dónde se cayeron pedazos de pintura, y eso no "sale con polish".

I purchased Meguiar’s Mirror Glaze M105 Ultra Cut Compound for correcting heavy swirls and paint defects, and the performance is excellent for a product in this category. This compound has strong cutting power and works quickly to remove deeper scratches, oxidation, sanding marks, and heavy swirl patterns. It is especially effective when paired with a dual action or rotary polisher. The formula cuts aggressively but still finishes surprisingly well for a heavy compound. On most clear coats it leaves only light haze, which can be easily refined with a finishing polish like M205. The working time is good, and the compound does not dust excessively when used properly. A small amount spreads far, so the 8 oz bottle lasts longer than expected. M105 is also versatile. It can be used by hand for spot correction, though machine application produces the best results. I used it on several vehicles with different paint hardness, and it consistently delivered strong correction with minimal effort. Even deeper defects that other compounds struggled with were noticeably reduced or fully removed. Wipe off is manageable as long as you do not overwork the product. It performs best on clean, cool surfaces and delivers a noticeable improvement in gloss even before finishing polish is applied. The only drawback is that beginners may find the learning curve slightly steep due to the fast cut. Using the right pad and speed settings is important to achieve the best finish. Overall M105 is a powerful and reliable compound that delivers professional level correction at a great value. For removing heavy defects and restoring clarity to paint, this is one of the most effective products you can use. Highly recommended for enthusiasts and detailers who want strong results with controlled performance.

This item is amazing! I use it to polish my resin items and it gives me a glass finish after sanding up to 1200 grit. I really recommend it for those who are making epoxy resin pieces.

Good product for rejuvenating aging paint back to its luster without being too harsh. Fast delivery and a fair price.
