What is the best and most efficient way to tighten the NMO permanent Mobil Mount ? Having a hard time getting it tight enough so it doesn’t come loose! Tried a long nose plyers but can’t seem to get a good hold on the very thin part of the mount that is setting on top of the car roof , then there is the threaded part of the mount on top of that .

They make overpriced tools that will work:
But you don't need one of those. Never seen anyone use one before...
I use a small pair of needle nose pliers. One pair I have has them at a 90º angle. The two tips of the pliers go in the two recessed holes in the center part of the mount. That'll keep the center part from turning.
Then use a wrench to tighten the outer ring.
Make sure you have the silicone lube on the O-ring before doing this or it can bind up and tear. And it doesn't need to be 'white knuckle" tight, just snug is good.

We have constructed this NMO Antenna installation tool out of stainless steel. This is made from stainless steel and works flawlessly. I believe this is the tool an antenna installer needs for NMO antenna bases.

Yes, you can tighten the nut or the butt, it's up to you….
There should be an O-ring on the underside of the nut. Before you assemble the NMO mount, make sure the O-ring is properly in place. A bit of silicone grease on the O-ring does two things:
1. It'll hold the O-ring in place while you assemble the mount.
2. It'll lube the O-ring and keep it from binding up as you tighten the nut.
Some manufacturers include a small blister tube of the grease in the kit, some do not.
Thankyou
Antenna Specialists used to include the "tool" with their antenna mounts. It basically amounted to a bent, heavy springy wire.
Another manufacturer's (maybe Motorola) mount was flat on opposite sides so you could hold it with a Crescent wrench.
I've pretty much just used the 90 degree needle nose pliers trick.

I have always just finger tightned the brass ring while pulling upwards until I can't turn it anymore. Then a snug with a wrench. I haven't had issues with the mount turning and haven't needed a tool. The pulling upwards thing allowed the teeth on the bottom to grip just enough to keep the mount from turning. By the time I am ready for the wrench, the teeth have already bitten and good to go

At one point I had one of those, but not sure what happened to it. I keep thinking of making a new one, but I always forget. I've got to install an NMO in my brother in laws new truck today, so maybe I'll see if I have some rod stock that is the right size.

3/32" rod works. Found an old antenna whip that was 3/32nd's and just rolled a couple of my own.
But the needle nose plier trick works just fine.

Roll your own out of an old antenna whip:
The K794 thick roof mounts still include the tool. Have lots of them laying around
