Heavy scratches.

I took the Dewalt to my mom's beater earlier to do some practicing. I was working on the trunk lid when I noticed three heavy scratches along the left rear door. It looked as though she scraped something, but they passed the "fingernail test," so I tried cutting them. I was running a wool pad at about 1400rpm and used 3m super duty rubbing compound....that really gritty brown stuff. I managed to almost completely remove one of the scratches, there's still a mark, but it's barely noticable. The thing is is that it took FOREVER. I know it takes a while, but is there anything I could to speed things up? I don't want to run the buffer above 1800rpm if I don't have to. I was thinking of trying OHC. How quickly does this work?

To any Carbrite users, has anyone tried their Liquid Machine Compound? Our supplier at work is coming on Wednesday so I was thinking about trying some of that.

Holy ****! wool pad? 3m super duty? any scratch if it was gonna come out, would of come out in no time! how long is long? try wetsanding it next time to level down the paint.

Should I maybe up the speed a bit? I'm not sure, but I think the bottle said to run the buffer at 2000...a little high, but I was thinking around 1800 and apply pressure?

I'm going to try a foam cutting pad later. The wool might be worn a bit, so hopefully the foam will take it out.

I didn't exactly keep time, but I want to say that the one scratch come out with about 5-8minutes of cutting.

how big was the area? no no.. dont up the speed! 1200-1500 is good.. i could cut through anything to the metal if i needed to @ 1500rpms. 5-8 minutes is a lot.. i hope it was a big area.

You might have used too much compound... that'll slow the cutting down significantly, as the extra polish serves as a lubricant and prevents effective cutting.

Well, I just came back in. I tried using less compound and it did make quite a difference. There's still some scarring left from the scratches, but they are greatly improved so I decided to leave them where they are. Thanks for the help!
