3M Auto Care Rubbing Compound, 03900, 8 oz

i've always liked 3m products, and this one did not fail me. i used it with my Porter Cable dual action polisher and Lake Country CCS yellow cutting pad to start detailing my wife's 2006 Subaru, which was purchased used, and on which the paint was already looked pretty blah . I had wet sanded with 3000 grit 3m Trizact sand paper some of the deeper scratches first, which left those spots rather dull and full of finer scratches. My first step after that was to use this compound. It took out all the fine scratches from wet sanding as well as all the swirl marks on the car, leaving the paint looking great. I was pretty impressed. The areas that were wet sanded needed to be gone over slowly with a decent amount of pressure, and sometimes i needed to go over them a second time with more compound put on the area, but they got out. The areas that just had swirl marks were smoothened out fairly easily, but still going over the area a few times within the same "pass."Which brings me to one point - you have to use this methodically. check out youtube on proper compounding procedures with a DA polisher, and you'll see how they move the polisher slowly, covering the same spot multiple times in one pass. Think about what you have to do when you sand wood. it's no just a quick swipe over the area. You have to go over it a good bit before it's fully sanded down. This is the same concept. You're essentially sanding - very fine sanding - the car's clear coat.I polished after this step, but honestly, it didn't look much different. which is to say, that this compound leaves a good finish. You do want to polish to further smoothen out the clear coat, so don't skip that step.The only "negative" is that there's a lot of dust that come from this, but seriously, i haven't dealt with a compound or fine cut cleaner that doesn't. just have a bunch of microfiber cloths handy to wipe it down.

I have been a very loyal purchaser of this product for years. I've bought the Meguire's scratch remover, many polishes, many waxes. Nothing comes close.I live in a crazy beach environment. Thanks to tourists and drunk people the only parts of my 2009 Jeep Liberty than haven't been repaired and repainted are the hood, roof, and rear gate. It is constantly hit with car doors, inflicted with unexplainable scratches... but it's paid off, has been a good car, and I want it too look nice for as long as possible.A car wash put a four inch deep scratch in my hood. I have a new bumper swipe on the back from someone who couldn't parallel park, and there are deep scratches in the left painted plastic fender (maybe a bike?)This rubbing compound shined the scratch in the hood so it's barely noticeable. Sure there is a scar in the shine when looking at an angle, but the noticeable white scratch is gone. Same with the fender although the plastic took more work.The rear bumper cleaned up great. Oxidation from parking on the street in salt air is a breeze.I'm not a body technician so I wouldn't be comfortable using power tools with this. It's so effective by hand that with tools used incorrectly, I know it could burn right through the paint.It is exactly what you would expect from 3M and it works. It might not make some types of damage perfect but it's the best thing on the market for making it better.

I love 3M automotive products. They are the best in the industry and nothing compares to their Perfect-It products. I had high hopes for this rubbing compound. I had been using a Meguire's cutting compound which cuts quickly. I wanted to try a 3M product, but this is a little mild for my taste. I was only trying to polish plastic lenses on which I had worked up to 5000 grit sandpaper. It took three attempts with a 3" orbital polisher before I was confident that I could finish it off with 3M Perfect-It #3 ultra-fine polish. That's a lot of work. I would have preferred a more aggressive compound. It's great otherwise and you may want a very mild compound. If so, this would be great. I wanted something more aggressive.

I used this to get rid of the haze on old Honda Element headlights. Easy to use and did the job. I imagine I will have to use it again with time but was very happy with results.

EXCELLENT! On vehicle they completely r remove light surface scratches and beautify headlights, I would highly recommend this product if your headlights have slight yellowing

Goes on good and seems to be the trick. You have to use some elbow grease to get it off and rubbed in good. All was good until I washed my car the next week and it seemed to leave a film and it was even more elbow grease to get those off. Now it looks just like it did before scratches and all because I just do not have the time to invest in reapplying. It was a good temp fix!

This stuff is magic!Like many reviews have stated - I saw the same YouTube video using 3M buffing compound to renew weathered headlight lenses.I've owned my car (since brand new) for 17 years. Despite the fact that it has never been garage kept; It sill looks as new as the day I bought it. The only dead giveaway of it's age were the hazed over, yellowed headlight lenses.Applied with a simple t-shirt, hand scrubbed and polished , in less than 10 minutes my headlight lenses were absolutely crystal clear with no yellowish tint.Just a side note: There are no aftermarket or OEM replacement headlight LENS for my car. The entire headlight assembly; New or Used, has to be replaced. Ebay "pre owned" = $189 ea. New (OEM)/aftermarket = $298 - $400 ea.Under $20 +10 minutes of my time + an old t-shirt = like new results.....You do the math ;)
