I am new to detailing and I want to buff my vehicle. I have VERY LITTLE exsperience with a buffer. It is my understanding that I need a "Dual Action" buffer so I dont burn the paint right? At least until I get experienced. Can I use any kind of buffer as long as it has the speed dial? One from Wally World, Lowes, etc...? I prefer to keep the cost under $100 if possible.
