Grease or loc-tite

Hi,
Opinions wanted.
I just bought a new 10mm QR skewer to replace the old one that got threaded.

Should I put grease or loc-tite or nothing on the threads?

Grease 'em up, son!
FWIW, the only thing I ever put loc-tite on was the little grub screws for brake lever adjustment. I think most crank bolts ship with loc-tite too.
I'd use grease....
I wouldn't use Loctite on this. The cam mechanism on the quick release provides more than enough tension force to lock the thread. That's the whole point of the quick release, so you don't need to tighten them.
Using Loctite will just fix the thread in a single position and prevent you from fine tuning the cam tension. This could result in either stripping the thread or a wheel that's too loose.
The thread should be slightly loose before you tighten the cam otherwise you may damage the thread.
A bit of grease will help stop the thread from seizing over time.
I'd go one step further than grease.
Any thing that screws into Ti or that Ti screws into needs anti-seize or moly paste on the threads, or it will gall.
What Hawkeye said - I use Finish Line anti-seize/anti-galling.
Overwhelming support for grease!
Then... Should I use a grease or chain lube sort of thing?
I personally work in a bike shop and can tell you that we will only use proper grease (not chain lube type stuff) on quick release skewers. Make sure it can slide easily through the hub and does not feel like there is metal on metal (it should be greasy smooth) so don't hesitate to use a little more (as long as its not overflowing everywhere) grease than you would think.
Chain lube is too thin/viscous. Grease will be better, but for things like that, I use Shimano anti seize paste.
Anything thread/pressed that can hold a lot of torque or are subject to great force should have anti seize. Bottom bracket, cranks, QR, headset, pedals.
Small nuts and bolts that should stay put that can't be excessively torqued: thread lock.
Bearings that are subject to low speeds but high loads get grease. BB, headset and wheel bearings.
For everything else (chain, hydraulics/pneumatics) i use lube.
If you're going to use grease, make sure it's a high pressure grease (bearing grease etc, anything will work, but a HP grease will work best), as said, an anti-sieze would be good too.
If you using titanium parts (which i assumed you were) then use anti-galling (anti-seize) compound. If not then grease. If you likely to ride in wet conditions (standing/flowing water, mud) then suggest you use Boat Grease or "water proof" grease used in some trailer axles. I use this behind the bearing dust covers on wheel bearings, BB, and skewers. That way the grease resists the water, stops dust getting behind dust covers. Bit messy to clean (every couple of months depending) but can be worth the effort.
