Fix the problem properly. DO you really want copper and magnese flakes running around in your cooling system, destroying impeller seals and clogging rad cores, not to mention smelling like shit when you turn the heat on?
I can't believe you added that shit to your motor...

I also have had no luck with any sealant additives. They clog everything. Most notably the radiator and heater core, but occasionally the hole you're trying to seal.
In order to lessen the problems for yourself I would drain your radiator and flush your coolant system. Then I would fix your head gasket. Head gaskets aren't that hard to do.
The only time I would recommend sealer products such as the one you used is on something like a 30 year old farm pickup that you're hoping to get another few thousand miles out of before trashing entirely.

well, my 240sx seem's to be running good after the gasket fix seal.
engine is purring and the car accelerate's pretty good, although i shouldn't be doing so.
should i expect it to last? or consider it a temporarily remedy?
It may hold if you're relatively easy on it. But look at what had to happen to fill the gap in your head gasket...it filled a sizable gap. Think about all that crap still circulating around your cooling system, clogging radiator passages and your heater core. Drain that shit out immediately! It's done all the "good" it can do and the longer you leave it in there the worse things will be for you.
That's the problem with these sealer products. If they work they seal a bunch of other stuff you don't want sealed also. If they don't damage your coolant system then they also don't seal your head gasket leak...
Get ready to replace the leaky water pump. I guarantee that fix won't hold. It's probably the bearing seal going out from a bad bearing so it will need replaced soon. If it was leaking at the gasket it may hold but being torqued on by the drive belt constantly under load it'll probably wear loose anyways.
And I didn't mean that the leak sealer = instant engine death, it's just not good for it and will create a lot of long term problems compared to fixing the head gasket. Head gasket sealer is a hell of a lot better than radiator sealer because head gasket sealer generally has small particles that require 300+ degree temperatures to harden. Radiator sealer doesn't and fills a lot of passages you don't want filled. It's good you flushed the crap out but I surely wouldn't consider it a permanent fix. Now that it appears to be running fine you could sell it as being in good operating order if you don't believe in Karma.
