It has enough power to make a good finish great.
It does not however, make neglected finishes sparkling new again. Thats where high speed direct drive buffers come in handy. With training and/or practice, these direct drive buffers can become your best friend. If careless and inexperienced, these buffers can burn paint, and make the car one big swirl mark.
I assume that your truck is in great condition. The PC will make it even better. As in prepare the surface to almost perfection, perfection we all achieve for, but come short of, ever see a 100 on a car that went through Concours events? I doubt it, maybe a few 99.98's and 99.8's, but I doubt someone ever got a 100, there is always that one speck of dirt the judges find.
The Porter Cable is a dual action buffer. Its head moves/oscillates in two directions at once. Visit
www.meguiars.com for the power buffing tutorial. Same machine, just re-badged and marked up a few hundred percent.
The machine is very user friendly, after a car, you will get to know the machine. its also a good exercise machine, after hours of use, it tones up the arms, mostly forearms.
There are lots of threads about this, do a search, "Porter Cable", "PC help", "PC techniques".
Most people here go to
www.coastaltool.com for the machine, and
www.properautocare.com and order the DM-KIT, also get the 6 inch counter weight if you get the DM-KIT because now CMA ships 6 inch backing plates, I use the 5 inch counter weight because I have the 5 inch backing plate.
Happy Detailing,
