Depends on the car for me. In some heads, the sparkplugs like to stick, mainly due to design IMO.

But the discussion about using this is similar to whether or not it's a good idea to use it on wheel studs, etc... There will always be people on both sides of the fence.
The main reason I use it is because I had to remove a destroyed spark plug in a V8 when I was in highschool and helicoil the head. That sucked.
If you decide to use a product like this on spark plugs, just make sure that you use a COPPER anti-seize as it allegedly won't foul O2 sensors etc... And if you do use it, a little bit goes a long way. I apply it all the way around the threads/seat with my finger, then remove the excess with a paper towel. This leaves just a little bit in the bottom of the threads. Works for me, YMMV.
