Question is was this a good idea or not.. seems to be holding tight for now but worried it may acttualy effect the beer.

Thanks in advance for the advice
So it might do the job in sealing, but further down the thread is this:Cured cyanoacrylate (superglue) is non-toxic, but it's also pretty fragile and very slightly water soluble, so probably wouldn't do a good job.
I'd say, a good idea to get the seal back on the keg so you can continue enjoying the beer, but as soon as the keg's empty, I'd replace the lid.One big concern was that with a sealant, you'd get a lot of little hard-to-clean nooks and cracks, perfect places for bacteria to accumulate.
