Is there any reason to believe that Apple would deny any warranty repairs due to these adhesive strips not being identical to Apple's? I'd like to open and clean my iMac before taking it in to have the display replaced under warranty, but the vibes I'm getting from Apple support suggest that Apple may deny me service if the adhesive strips 'show any signs of tampering', i.e., being replaced for any reason. This sounds silly to me, as it doesn't void Apple's warranty to upgrade my hard drive.
