Ok, i got my new dewalt 849 in the mail and i tried it for the first time on my friends vw, the paint came out really nice but it didnt remove all the swirl marks like i thought it would have, I use the yellow polishing pad with DACP at about 1200 rpms? my question is this right ? what speeds do you all usually use with what products? i use almost all meguiars products. thanks for the advice.

HBblazer you must be reading my mind. just got my dw849 this week also. tried it out on wifes suv with green edge pad. i set my buffer at about 1400 rpms and i was going to post to see if that speed was ok. i was also unable to remove all blemishes from the clearcoat. you said you used the yellow pad was it a meguiars pad? if not what brand was it?
 
With DACP I usually use it anywhere from 1400-1800rpm with a Meg's yellow or equivilant pad.

Since you just got the polisher, you should continue to practice as lower speeds and gradually turn up the speed. Products such as DACP work better at higher rpms which tend to break the products down better.
 
I have a DW and did the wifes black BMW yesterday using a orange cutting pad, with SSR2 and removed almost all the swirls.

You have to work the product well over the panel. I then went to a polishing pad with PB P-w-C worked well and followed up with a carnuba paste wax. I could see a few swrils but very little

Bozack- i was using a meg's pad

Thanks hbblazer. i just had a problem with another pad so i'm going to try a meg's pad. have you tried any other pads? and if so what pad worked best for you?
 
You are probably not spending enough time on target. You need too 1) Heat up the surface enough and 2) Let the polish break down until its almost totally gone. Most beginners make too fast of a pass over a area. It is best to learn this technique on the slower speeds with a lighter pad and light compound and stay the hell away from the edges until you get the instinctual feel for it.
 
Well i actaully had the oppertunity to do an old mercedez the other day, it was a friends and he trusted me , so i went to work. The car was red and extremly oxidized, there was no reflection on the paint at all. I used my rotary, megs yellow pad, and megs compound power cleaner, or whatever its called, it came out fantastic. The paint looked like its old self again. I wish i had more time to do another less abraisive polish but she was only going to pay me for a wax. I really need to get a digi cam. Yeah, when i first used the rotary i was afraid to do damage, but after i got the hang of it, it worked really nice. Im almost ready to start my business so ill have to borrow someones camera and take pictures of my trailer and equipment. thanks for all the advice
 
the rotary

Hey HBblazer
Another thing you want to watch out for is stuff like moldings, antennas, windshiled wipers, mirrors, plastic bumpers, or just about anything plastic or rubber.
If you are using a foam pad it doesnt take very long to burn the paint on any of those spots.
Take your time and you'll be alright.
Or just tape things off that your not sure about.
I'm pretty comfortable with the rotary and usually dont tape off much any more but i know my limits and will pull out the tape if I dont feel safe about something.
Hope this helps a bit.
 
I think it is important to use different speeds for different sections of the car.

On flat sections with a lot of space using DACP around 1500-1700 rpm can do the job. Where as in smaller, curved or raised areas dropping the speed to between 1200-1400 and using very slow passes allows you to easily control the heat the buffer is producing.

I have found that as well as using the right technique and buffer speed, how clean you pads are, amount and right type of product are very important. Also trying to buff too large an area can make life harder also.

one thing to also keep in mind. Always use a different pad for different products sometimes this can cause buff marks or holograms in the paint. It doesn't happen to often but can happen...
