Anyone know a good fix/lubrication for the Rear Hatch lever. Mine is sticking.

 

I don't know the best answer to this one as I haven't experienced it, but now that you've got this thread you should see a number of links down at the bottom below "reply" that cover the same issue.
if there's corrosion that's mild, I'd recommend 3m's maroon "very fine" scuff pads paired with a little wd40 on it to remove said corrosion and give you back a surface that looks machined. Their grit equivalent is somewhere between green and blue pads on kitchen sponges, but I wouldn't recommend using either of those.

If it's a matter of lubrication, silicone paste/dielectric grease are to my knowledge the same thing, and also the recommended lubricant for the rams/pistons of shocks/struts/dampers. For general lubrication (like a hinge) I'd recommend a waterproof chassis grease/marine grease, but white lithium grease has also been recommended by some auto manufacturers because it doesn't draw dirt. Does still get dirty over time.

If you're lubricating a lock mechanism, I'm not sure what's best. I've heard that dry graphite lube is used by some for ignition switches because, well, it's dry. I feel like silicone could also be used, but if you're using an aerosol can it'll also have solvent in it and it may be in your best interest to disconnect the battery first and wait for the stuff to dry (which doesn't take long at all).
Some folks recommend WD40 for locks, which has great penetration but seems to dry out/gum up quickly, requiring reapplication (prolly cuz it's so thin.) I'd also be worried about it causing an electrical short if spray could reach circuitry.
