Plenty of tips on the internet/youtube bud, ammo nyc on you tube has some great tips for it and he works on anything from mercs to veyrons so hes pretty damn good at detailing. But an dual action polisher and a compound is when you need, if youve never machine buffed before make sure you dont use a rotary polisher though as you will burn the hell out of your paint and ruin it. Rupes 21 or 15 are the best I believe, dont think I can post links yet as im a newbie but 'chemical guys' do a good explaination of all the polishers. Do it in 4 steps as well, so coarse compound, polish, finishing polish and finally wax to protect all your hard work!
Few other tips are:
1. Use two buckets when cleaning your car (one clean, one dirty).
2. Start from the top and go down.
3. Chuck away whatever you're using if its stinking!
4. Dont use circles! They are much harder than straight line scratches to get out.
5. Clay bar your car.
6. Only polish once every three months at most.
7. Wax whenever you want cuz the more protection the better, I aqua wax mine after washing once a week and use turtle wax once a month.
Hope thay helps buddy
