A Porter Cable 7424 is probably the best investment any detailer can make in my opinion. You’ll be completing better detail work in less time, while using less energy. The Porter Cable 7424 has quickly become the industry standard for both professional and weekend detailers alike. The PC 7424 is a very durable machine that comes with a one year warranty, only weighs 7lbs, can adjust the speed on the fly, is easy to hold and is very user friendly. The PC excels at removing swirls and fine scratches, when working in a polish. Unlike waxes, sealants and glazes, polishes have micro abrasive particles in them that require more pressure and heat to break down and be worked in to the surface evenly. Completing an equivalent job by hand is very difficult if not impossible throughout an entire coat or multiple coats. Your hand gets tired and you generate varying levels of pressure and generally complete far less passes. Can your hand operate at 6,000 oscillations per minute for hours on end?

The Porter Cable 7424 generates low levels of heat unlike traditional rotary buffers that can easily burn the clear coat or paint. This buffer oscillates in a tight random orbit motion, which creates safe levels of heat and it’s very easy to control. The buffer should be used with different textured pads that can help build optimal levels of heat for each step in your detailing process. For example a strong cutting polish should be used with a firm foam pad for maximum cutting power, while waxes are applied with a much softer pad. The Porter Cable 7424 has a dial to easily control the speed it operates depending on what step in the process you’re doing and to accommodate the skill level of the operator. Polishes are typically applied at higher speeds (4.5 – 6) while glazes, sealants and waxes are more commonly applied at speeds (3 – 4).
