The reason I ask, is that I'm a newb, and have just finished collecting everything I need to start detailing (pc 7424, pads, *backing plate*, polishes, etc)
I just received my order of pads, polishes and backing plate from AutoGeek. However, they sent me the wrong backing plate. I ordered their model LC-43-125DA 5" backing plate
Dual-Action Hook & Loop Flexible Backing Plate 5" because it was supposed to be flexible and had two good reviews. Instead, they sent me a 5" backing plate made by "the edge products"
Dual Action 5 Inch HD Backing Plate.
The backing plate that was sent seems to have no
flex at all. It may if you really really lean on it, but I can't imagine using that much pressure on a cars paint.
So the question is, are most backing plates like this? Or do the actually flex when pressure is applied. I recall reading that
Sonus plates only require .15 lbs/in. befopre they start to flex. I would imagine that the one I received takes between 8 and 10 lbs/in. before there is any meaningful deflection.
It would seem to me that especially as a newb, it would be beneficial to have a plate that deflects as much as possible, so as to not apply too much pressure on any one part of the pad especially given what are likely to be my unrefined techniques.
However, this may be what they are all like, and I just haven't seen enough to know.
All advice is appreciated.
Cheers.
How much flex should there be in a backing plate?
