If I'm not mistaken, you originally used a 6.5" pad with a 6" backing plate, but then suggested a 7" pad with a 6" backing plate is better?
Sheesh- I can't recall if I sent you that in a PM or I posted it online...
I used all sizes of pads, even cutting some to the same diameter as the backing plates I had in my arsenal. The largest one I had in my possession at the time was a 6" diameter plate. Actually, it was a Mirka plate that measured
5-13/16" across.
Keep in mind that even if you just slap the pad onto
any backing plate, it's gonna
work. Optimally, try to support the pad as close to the edge as you can.
If you are not comfortable polishing difficult areas using this non-staggered setup, match a backing plate to the pad that still allows you to comfortably polish difficult areas, such as those that transition from horizontal to vertical (bumper cladding is an example).
Note:
A "staggered setup" is when you use a backing plate that is a lot smaller in diameter than the pad.
A "non-staggered setup" is when you use a backing plate that is the same diameter (or very close to the same diameter) as the pad.
We are "splitting hairs", so to speak.
Ironic, considering the fact that most of my hair
has split... the scene. Boo Hoo
