Time to revisit this issue. I too became a Peli M6 user a year or so ago, after being informed of its modding potential. Eventually got a few M6s shortly after.
Now one of my M6's boot starts to show some wear (it becomes less firm, softer and maybe a bit "sticky" in touch) so I contact Peli for possible replacements. However, two emails later and still not one single response. Unfortunately I can't call them because I'm out of town for extended periods.
Can someone help? At worst, I may have to consider having this boot cloned by a third party.
