My paint is dull. I waxed my car yesterday with the 3 step Meguiar's thing but it didn't do too much. I've read of guys whom wet sand and buff and all that good stuff. What do you guys use? What grit of sand paper? What buffer do you recommend? I saw a $35 buffer at Wal-Mart, are they any good? Any tips to get this done right will be appreciated.
