Hey guys,

I have 24 year old paint work on my car but has no rust and just looks a little scratched (typical swirl marks). How would I go about machine polishing/cutting it? Never done it before but I have seen fantastic results. My paintwork isn't faded or anything so I thought I'd give this a go.

What type of, Angle Grinder, angle grinder 'bits/discs', Pads, polishes/cutting solutions, sandpaper, etc, etc will I need?

The technique I can develop by watching vids on youtube, its just collecting the apparatus that I have trouble with. I plan to take all the trim off whilst I do it so, big operation :)

Cheers,
Daz

Found this vid to demonstrate how to use 3M stuff. His obviously not chatting rubbish as the results speak for themselves but, is there anything anyone can add to this?

Be careful Daz, I think the angle grinder may spin to fast and if you catch the trims(rubber) it could "score" them beyond recovery !!

could say ive done this before lol
im a painter so do it every day and with a award under me belt to it goes to show i no what to do.
ideally you need a DA or rotary polisher, always start off with a polish with the least cut in and work up if need be.
just cause that fella got good results on a video doesnt mean you will. its not as easy as it looks and takes alot of practise and usually alot of mistakes happen along the way, but thats how you learn.
