PROS & CONS: Porter Cable 7424XP 6-Inch Variable Speed Polisher Review 

Porter Cable (PC) is a trusted brand and has continued to produce quality buffers for detailing pros and beginners all around. The PC 7424XP Variable Speed Polisher is one of the best on the market for detailing products. The latest model is faster and does not over heat, easing your mind from worrying if the paint will burn.

It has a better design that ensure comfortability and easy use. The trigger is well placed and makes for a easy transition from one position to another while removing swirls and oxidation from your car. The 7424XP also features all ball and roller bearing construction with spiral/bevel gears.

Pro Highlights

  • Ideal choice for beginner
  • Variable Speed (No load Speed)
  • Heat Overload Protection (wont burn paint)
  • Random orbit, swirl-free sanding/polishing action
  • Accepts 5/16 – 24 spindle thread accessories
  • Features two-position (left or right) removable side handle for greater comfort and control


If you have some major detailing to do in one shot, this isn’t the car buffer for you. Although it comes with a foam pad, you may have to purchase additional pads within a couple of months. Detailing your car can be a daunting task but buffers are suppose to make the job easier and even fun, so choose what buffer is best for your job/jobs. The PC does vibrate a lot, this is one of the reasons many car waxing pros opt for the Flex Polisher, it all depends on your level of expertise and job size. Also, with the vibrating comes loudness.

Con Highlights

  • Not the best for heavy duty work
  • Might need addition pads soon
  • Vibrates
  • Loud

See Manual

Overall, you can see why the Porter Cable 7424XP 6-Inch Variable-Speed Polisher is so popular amongst novice and professionals.

It has you need included in the packaging and, with its design it beats out many competitors.

Still, the handle, pad and vibrations leave some car detailer leaning towards other buffers on the market. If you are a beginner trying to make a name for yourself, this is the best car buffer you can get for quality and great price.
