Has anyone tried using a polish with added colour together with an electric polisher, I was thinking of getting one of the two handed jobs rather than a simple attachment to an electric drill.

The body colour is dark blue and shines up reasonably well but has a few surface scraches and a nice keyed white line running the length of the car, bless his hooded little head

Use that polisher an youll have even more scratches!!BIG NO NO USING POLISHERS!!

Have a look around:

They have all the answers for cleaning, polishing etc.

Rotary polisher will bring the paint back to a nice shine - NMT60 I've not had this problem that you describe using a rotary buffer it is not a big no no in my book - sure if you use an aggressive polisher you could leave buffer trails but follow up with a less aggressive polish to remove them. Keep the polisher moving and start off with a soft mop while you gain confidence.

Forget the colour enhanced polishes that is just marketing bull. Something like a colour restorer polish and Autoglym Super Resin Polish would be a good starter.
