The PC7424XP is a great machine to start with when you get serious about car care. I don't know how many times I've told people that the $50 "buffers" they find at AutoZone and Sears are absolute crap when it comes to actually repairing damage to your paint. You've got the right tool for the job for sure. The Meguiar's Ulimate products are awesome too. I think you'll like them. Get a bottle of the Ultimate Liquid Wax as well. It is actually a sealant, so don't let the word 'wax' fool you. It is an awesome product and will give your paint some awesome protection after you put all that work into making it pretty.
