It depends on how bad they are and how hard your paint is if DACP will remove them. Have you noticed any improvement?
Here are some keys to how *I* use DACP. Start with a speed of about 3-4 to spread it around in a small area (about 2’ x 2’). Then bump the PC speed up to 5 or 6 and make very slow passes (SLOW is the key here) until the DACP virtually dusts away. You may have to do this 3 or 4 times. If you don’t notice an improvement then you might try a yellow cutting pad. If that doesn’t help you may need something more abrasive like SSR3. If you have really, really hard paint like a late model Audi then a Cyclo or rotary may be needed.
After using the harsher pads/polish you may need to go over it with a polish pad to remove any hazing that was created and also follow up with a milder polish like Meg’s #80 or SSR1.
