Do you guys use some sort of lubricant on your decklid shocks? I noticed mine just got quite stiff when closing "and" when also opening the decklid. Usually with these D95004 brand it took one finger on the hood to guide up and down with the hood. A couple weeks ago I applied some grease and after a few up and down of the hood, it was back to normal easy slide. But now two weeks later it was kind of stiff again, ready for more grease, in which it slid better again after applying more grease and working the hood. Maybe WD40 or something else would be better, or last longer?
