My suggestion is to invest in a Porter Cable instead of the drill powered polishing application because the consistency won't be the same throughout the car when polishing due to the battery life of the drill dying out. Return that, get your $50 back and spend another $100 or so to get a Porter Cable with different pads that will be necessary for cutting, sealing, waxing, etc etc. You can sell it on the forums if you'd like down the line, that's what I did and take about a $20-$30 loss but it was well worth it. Just my .02 cents
