I picked up a new backing plate at Car Quest today when I returned some stuff that was wrong. After putting this 3M Hookit backing plate on my 7424, the hook and loop is backwards. The backing plate has the same part of the fastener material as the pads. My other backing plates have the stiff plastic hook on them, this has the loop. Is that common for 3M backing plates or did I just get a bad one? (Everything I have bought at this Car Quest has had to be returned so far). It is the only place in my city to buy any detailing supplies.
