Just my .02
Thanks bud for the crystal clear explanation. As I type this I am waiting a shipment of Mobile 1 grease from AliExpress so that should be interesting in the days to come. You basically just wrote what were my concerns with greasing the components up; dirt and all that gunk in the components thereby increasing the need for more preventative maintenance.... which I am not a fan of. Oh well, gotta give and take in this hobby I guess. Hopeful that other members could chip in on this subject too. Cheers guys.
