if you were using G3 or similar its very abrasive (hence the swirls) and you need to finish with a finer compound (eg G7, or t-cut) and then wax it
Dude don't waste your money, just give it a good t-cut and then polish/wax it twice over. If you keep going at it with rubbing compond you'll be taking off more paint than you need to. One more thing regarding the t-cut, do not let it dry once it's on or it'll be a total cow to take off. Put it on ya cloth work it into the paint then buff it straight off, then just wax it and see the difference.
will bare the bodyshop in mind but i think it will feel better if i did it and went... WOW! lolFrom experience T-cut is ok, but nowhere near as good a finish as buffing.
The 1 i use is a Bluepoint/Snap-on. It cost about £120 i think, its variable speed and quite light so doesn't make your arms ache. Lol.
A guy i work with gas a Milwackey ( i think thats how its spelt) That cost him £200 about 5 years ago, but it's brilliant. Even lighter than mine, I always try and use his when i can.
You only want to buff your car probably once or twice so it's probably not worth spending that sort of money.
Have you tried your local bodyshop?
We charge £50 to buff a full car and then polish it and it takes a few hours to do.
