Hi guys,
I saw mention of Porter Cable (PC) and Rotary polishers in another thread, I thought I might give some info about these.
The PC is a dual action or orbital machine the advantage and reason the PC has become the standard is the size of the "throw" most orbital machines have a throw of between 6 & 8mm whereas the PC has a throw of about 24mm, this means the PC is basically an "open the box and use" type machine, the PC is also totally safe for use by novices anyone can use one without doing damage to their paintwork.
The Rotary polisher on the other hand is a "direct drive" machine which means the shaft that drives the backing plate/pad comes directly from the motor and here is where the problems can arrive, as it's a direct drive a lot of heat can be generated and if too much then the clearcoat/paint will be damaged, care and indeed practice on a scrap panel are essential.
One other point I would mention, we have now etailed several cars as result of these cars having machine (Rotary) polished by bodyshops causing what we call buffer trails & hollograms, the reason for that is they use the maching on much to high a speed settimg and move across the panel way to fast.......this is not me bashing bodyshops just our experience of their polishing abilities, basically I'm saying be aware when you car goes into a bodyshop.
The followwing is a link to a car we did and the damage is as a result of bodyshop machine polishing: -
