I've considered the hand impact driver as I actually own one, but I'm
tentative due to the aluminum case. Any positive/negative experiences?

The plug only sticks out 1 thread. It's been painted over, and from

tried valve grinding compound yet, maybe a combination of heat and

with a new oxide hex key with a ratchet will work.

Motorcycle people have many of the those plugs to deal with & swear
by the hand-impact drivers; you preload them with a twist and hit
it with a hammer. The hammer keeps the key deeply seated.

Buy a 1/2" square drive key from Snap-on or such.

I concur with the preheating but also suggest getting some Kroil
Oil from Kano labs. It makes Liquid Wrench look like mouse milk.
