Stuck truss rod nut

I usually try heat to loosen things up; it can break adhesives free and release moisture from wood to lubricate things.

Don't do this while the Kroil is on there, BTW, or you'll have a Bar-B-QCaster on your hands. :)

Chinese. Allen key type.

As a last-ditch effort, after you try the Kroil a couple of times...cut the L off an Allen wrench, so it is a straight bar. Insert it in the nut and give it ONE GENTLE tap with a hammer very gingerly. I can not stress, do not wack it, you are just trying to knock it free a bit. Hit it very softly and lightly. This should open up the threads allowing you to get the nut moving, if not it should open up the threads enough for another application of Kroil allowing the Kroil to penetrate deeper.

Also when you apply the Kroil hang the guitar upside down so the solvent drains into the threads of the nut.

Kroil or another good penetrating oil. Let it soak for 6 or 8 hours and try again. Also, try to tighten it first. Sometimes a stuck fastener will break loose if you tighten it first. It's an old trick used on exhaust manifold bolts on automobiles. Try to loosen exhaust manifold bolta without tightening first and they'll likely break. I learned that the hard way being stubborn when I was younger lol

Edit: guess someone beat me to the kroil suggestion lol there's another penetrating fluid I can't recall the name of that works amazingly well. You can watch it actually crawl UP the fastener threads from bottom to top. Trying to remember the company.

I cut them all the time with my Dremel. When I get an allen wrench with a bookshelves or piece of furniture, I always cut it and then stick it in the chuck of my screw gun to speed up the job. I am not suggesting he cut one from a nice set, but most people have some cheap ones in the junk drawer leftover from projects.

Why not buy a long T-handle Allen ?
