Buy this first. You won’t be sorry.

If you’ve got a badly oxidized surface, you need this. If you’ve got a lightly oxidized surface, you can still use this (with care). I don’t care what others say, this stuff will bring back your fiberglass. Be forewarned! With the right touch, this can be used on almost new surfaces. But if you don’t know what you’re doing, you can destroy a surface. Bottom line is: go light and careful. Increase the pressure and get instant results. But remember, you can only get out of your surface what remains there. If it ain’t there, nothing can bring it back.

Used this to clean my hazy, yellow headlights on my car. Works great, I just used my hands and a clean cloth but you could use a machine buffer to expedite the job. Make sure to tape off the headlight (I used blue painter's tape). It doesn't last as long as I had hoped (I live in California) and the headlights started to get hazy again after 3-4 months. However it only takes 10 minutes to do both lights so I just reapply the rubbing compound maybe once every few months to keep them looking shiny and new. In the pictures this was my 2nd time applying it to my car so the "before" picture doesn't look too bad. This works great if your headlights aren't too yellow/hazy. If yours are really bad I would probably opt for one of those headlight restoration kits and then to use this 3M rubbing compound afterwards to keep them looking good.

Works great !

Works great on boats ! First off don't use this if you don't have a good buffer , and if you have never compounded a boat ! Gel coat is thick on a boat not like car paint with clear coat ! It boats are really bad I will wet sand with 400 grit then 800 grit and then use this and then last use 3m wax finesse it and it makes a boat look new if you know what your doing it is a all day job. To a couple hour job . You can ruin your boat if you don't know what your doing watch some YouTube videos at least !

Works! Picture below

Have an old 96' BMW 328i that I am fixing up and the paint is in really bad shape. I wet sanded with 1200 grit sand paper first then used a buffer and applied the 3M super duty compound and I couldn't believe it. The paint looked brand new, can't wait to polish it up for a beautiful shine. Definitely recommend for anyone who has an extremely beat up paint job. In the picture you can see the top section of the car where I haven't applied and buffered the 3m compound. Below it looked exactly like the top section, all scratched up obviously, and now looks like a brand new coat of paint. Just be careful and cover up and trim you don't want buffed like the door handles or side molding. I used blue painters tape; worked fine. P.S. This stuff smells extremely toxic, a mask of some type is ideal if working with this for several hours.

Used this and some new polishing sponge pads on a Harbor Freight 7 in. 10 Amp Variable Speed Polisher. I had neglected my collector car paint for quite some time and it was in terrible shape. The pads along with the 3M rubbing compound brought the paint back to it's original condition. I am very pleased with it.

Removed all the dead paint on my 26 year old truck.

Worked very well to remove all the dead paint on my 1991 F150. I used a dual action buffer and it worked very well. My first time using electric buffer. Didn't leave any swirl marks. I finished up with some cleaner wax and the paint looks like new.

The product is for heavy cutting such as oxidized gelcoat on a boat. Don't waste your time on compounding gelcoat that is in very bad condition. It needs to be sanded first. Too many people will buff with a heavy cutting compound, such as this, and see a tremendous difference. In 3 to 6 months its chalky again because you can not protect the gelcoat until you get to unoxidixed gelcoat. Wax or sealants will not fully adhere until you get to a clean surface. Gelcoat does not oxidize in a uniform layer. It will create pits and valleys. Compounding will remove some the oxidized gelcoat and make it shiner. Even a washing will make it shiner. This product is very course and needs to be followed up by a finer compound. After a few years of annual buffing, all that may be needed is the fine compound and polishing compound.

Scratch Eraser

Car maintenance is somewhat of a relaxing hobby for me and while waxing or even mild abrasives can make the painted surface shine, I wanted to give a car that I was selling that almost new look. I had tried other products available in the car cleaning aisle but I had some deep scratches they could not touch. So I purchased an orbital buffer, hook and loop disc, and a set of foam pads and tested the 3m product. WOW what a difference. The scratches were gone and I followed the 3M application with a series of Pinnacle products with successively less abrasion until I applied the wax. I was impressed....and so were the buyers of the car. If my first experience was not enough, my daughter decided to remove ice and snow from her new car with a plastic ice scrapper. Apparently, I never told her that a tool meant to remove ice from glass just might damage the finish on her car. What a mess. I thought there was no way these would come out, yet following the 3M application, all scratches were gone. I was very impressed....AGAIN. In fairness, if the scratch you are trying to remove is extremely deep (to the point of removing paint), no polish is going to fix that but if it is confined to the clear coat, I have not used a better product. Buy good pads, clean them occasionally, follow directions, and you should not have issues.

Works as advertised

I used this to polish the aluminum pontoons on a boat. It was probably not intended for this purpose, but it worked, without damaging the metal. It does take patience and elbow grease. Remember, a little dot is way better than a large glob. Too much product, makes it perform worse.

Excellent polish to level deep paint scratches where nothing else seems to work. Great for headlights too!

This is my goto polish when my usual aggressive polish can't get deep scratches out of paint. I typically use less aggressive polishes, but when I need "muscle" to get deep scratches out, 3M rubbing compound always saves the day. I also use this when restoring faded headlights also, with an orbital polisher, then follow up with a lighter polish to bring out the ultimate in clarity. Excellent polish. Great to remove paint transfer scratches, deep scratches that other polishes won't get, for headlights, for scuffs on chrome and even stainless pots and pans in the kitchen. If you're a detailer, consider adding this to your arsenal of polishes for when nothing else will work on a deep scratch. Not sure how it will work by hand, but with an orbital polisher, it works very well.
