I've only clayed a few times and it was by hand. Recently I got a Griot's 6inch DA and I was wondering what everyone's results were with using the special DA pads that hold clay.
Is it safe to do to the paint with a buffer on a low setting like 1-3? I'd like to avoid claying by hand in the future, not sure if I was doing it too much on the same area, but it seemed time consuming and would wear my arm out. But the few times I did it I didn't go over the areas quick, I kept going at them for quite a few minutes.
Also, do you recommend claying on every vehicle before the polish and wax/sealant, or is it not always necessary? Keep in mind I'll be dealing with vehicles that have either never been clayed, or where it's been quite a few years if it has been done.
