moghm - this is the method I use to use for removing/hiding scratches by hand quickly.
- one coat of AG SRP on hole panel and work into most visible scratches for around a minute
- one coat of AG UDS and work into the area around the scratches
- one final coat of AG UDS, try and rub this one so most of the polish disappears so its easier to buff off and you should have a scratch free vehicle for a few weeks
- cover with collinite 915 for dark cars (i've got the same colour as you but on a e36 its called schwarz II). I found that this keeps the fillers locked in for at least ~10 weeks
