 Broke the second time I used it Polisher broke the second time I used it. I will be looking for another brand.  Something You should Know I just received the Porter Cable 7424 and started it up. It worked fine at low speeds [1-2 on the dial] but got VERY unbalanced when any higher speed was desired. The reason was the counterweight [installed by the manufacturer] was specific for a 5" pad. Now, I asked myself 'why would the factory put in a counter balance for a 5" pad, then install a 6"?'. I checked, and 6" wieghts are available...$3.99+$6 shipping. But that didn't answer the question of 'why?'. I believe that these 'polishers' were originally intended to be supplied with a 5" head of some sort...either a polishing or sanding head. For whatever reason, a 6" pad was installed and the original weight not replaced with the corresponding correct counterweight. So, be forwarned! THE 6" VARIABLE SPEED PORTER CABLE POLISHER 7424 COMES WITH A 5" COUNTERWEIGHT...to run properly a 6" COUNTERWEIGHT IS REQUIRED...AT ADDITIONAL COST! Porter Cable 7424 makes waxing fast with great results This product does an excellent job on car and boat finishes. I would rate it a 5 if it came with a hook and loop polishing head. If you buy this be prepared to spend more on either microfiber bonnets or hook and loop systems that use foam pads and you need to have enough to keep separate pads for compound, wax and polish. Easily cuts the time to wax a car in half. Prior to this I had a sears 10" orbital buffer. Truthfully there is no comparison. Documentation with the unit gives no useful info on how to use it for waxing but you can find lots of information on the internet.  great Never used a buffer / polisher of any kind before. But with a little practice, trying the different polishes and waxes, I was able to create the shine I was looking for. I just recently had my motorcycle repainted with a custome paint job, I was a little nervous, but to my amazement, It looks great. This polisher is great for any noob like myself. | |||||||||
