A little bit of background. I have been cleaning cars for the past 20 years. The reason I am using the term cleaning is because I am starting to realize that there is a lot more out there to do than I ever knew. For the past 2 years I have used a wax called Cherry Wet Wax that I apply with an orbital Craftsman buffer. I would now like to try a Dual Action polisher, and some new products. The 3 vehicles that I mainly will be working on is a 1988 Iroc Camaro, maroon, a 2008 Ford F350 black and a 2012 Ford Explorer black. All 3 have good paint with some minor paint defects, mainly swirls and minor scratches. My questions are what DA polisher would you recommend? What/how many pads should I get to start. What products would you recommend for dark colored vehicles? I would like to keep the initial investment around $300.00. Thank you for any input it is appreciated.
