I have 1100 miles on my Apex, 95% in primo snow. I just pulled my shock to install the heavier spring, and noticed what seems to be a oily film on the shock shaft. I've never noticed anything like that on a shock before, but it doesn't seem to be blown. I can compress the shock manually with my hands, and it returns very slowly, so I know there's some pressure in there. Just wondering if this is normal.
