Just a thought, are you using the right screws to hold your mounts on? Maybe you're using too big a diameter of screw and over stressing them?
Sounds odd that you can see a ripple on the outside from the screws, and that it keeps happening...
Since the mounts are moulded the mounting holes aren't drilled, and presumably there is only 1 mould tool, so the all the mounts you've have should be near as dammit identical to all the mounts that everyone else uses as well. I'm going to check on my mounts later and see if I have the same ripple effect going on?
