Rodney ... The video was cool, an amazing transformation. If it takes 200 hours to polish the trailer with the power tools, I would hate to think how long it would take to polish it entirely by hand ... would probably be like cutting your lawn with a pair of scissors!
Before you attempt your car ... maybe you could first practice on part of an Airstream trailer, then try it on your car. Might be easier that attempting to find another Krikham or a CSX to practice on ...
