Head gaskets fail on 9.5 out of 10 '95 to '99 model year Neons due to engine oil leaking from the back side of the engine. To the average mechanic unfamiliar with this common issue on these cars, it can very easily be misdiagnosed as a rear main seal or oil pan gasket leakage because that's exactly what it looks like. However, with respect to your overheating concern, the only thing that comes to mind is low coolant or leakage causing low coolant level. If you are going to replace the head gasket, you might as well replace the water pump as well due to the age of the vehicle, and the fact that the timing belt will need to be removed when replacing the head gasket anyways. You might want the timing belt replaced as well. You'll save a lot of money by doing all this at once, instead of replacing these parts in stages.

The alumiseal will not work for a head gasket.
Head gasket leaks are serious leaks, and need to be replaced if you've got a broken head gasket.
If you're overheating and believe it's a head gasket.
1. Check to see if you've got water in your oil. Pull out the oil dipstick. If it resembles chocolate milk and is way over the max for the oil level you've likely got a head gasket leak.
2. A compression test can determine if the head gasket is leaking if one or two adjacent cylinders have lower compression pressures indicating a leak.
However your symptoms may simply be
1. Low on radiator coolant
2. Stuck thermostat
3. Bad water pump.
4. Bad radiator pressure cap.
These are significantly less expensive repairs than a head gasket and so I'd have another mechanic check it. Don't know too many good mechanics that would tell someone to use alumiseal in their cars. Actually don't know of any good mechanics that would tell their customers to use that stuff.

Neons are notorious for blown head gaskets. I went thru 5. Normally if the gasket is bad you will see oil leaking around the gasket area. Are you adding oil more than normal? You may also notice a loss in power.
Have not heard of the product you mentioned, however this is normally a "quick fix" and will eventually need to be replaced.
Dodge has finally come out with a decent replacement gasket

look for loss of oil or oil leaking out of the head gasket. the car could possibly start overheating on a continuous basis.

Check around the head for any leaks, also check your coolant level, and see if your exhaust is white and smells sweet, if it is, then you are burning the coolant and your head gasket is bad and needs to be replaced, but you NEVER dump in anything to try to fix a bad head gasket.... never!!
