Great thread and lively discussion....
I've been detailing as long as the first modern orbital polisher (Porter Cable), was to be introduced to the car detailing world besides the Cyclo and the GEM back in the 1950s and the 1960s.
And "yes" I have an article on this that documents the history of this tool and how pretty much everything else is a copy of or evolution of this tool.
The Free Floating Spindle Bearing Assembly - The Story Behind The Story...
On the topic of whether a free spinning orbital polisher, no matter what the brand, can remove swirls and scratches or more specifically, can remove paint by
oscillation only, or in reality, vibrating or jiggling against the paint, here's my take, opinion and experience.
Even if a pad and a compound jiggling against a modern clearcoat could remove paint it would be so s-l-o-w and ineffective that it would be a waste of time.
I'm the guy that wrote the first how-to article on how to use the Porter Cable 7424 back in my Meguiar's days. I'm also the guy that stated in print that you MUST press down on the tool while maintaining pad rotating in order to remove below surface paint defects, i.e. remove paint.
Before I wrote this the common recommendation was to let the weight of the tool do the work. If you take a PC today and try to let the weight of the tool do the work you'll be standing by the car forever.
IF you want to remove below surface paint defects using a free spinning orbital polisher then the pad must do two things,
- Rotate
- Oscillate
That's my 2 cents. Feel free to agree or disagree but tell you what... I've never had someone show me how to remove defects with a pad only oscillating, which is only vibrating or jiggling against the paint.
I've seen guys say it works but I've never seen anyone prove it. And again... even if it did work it would be so slow and ineffectual that it would be for me... a waste time.
