Aluma seal or bars leaks ? ? ? ?

[MrMarty51]

Yessterday, running chores.
Man at tire Rama tells me he seen a drip from under my truck.
I’m watching out for this in my travels. Drips out the left side like coming from the radiator drain cock.
Put truck in garage, relieve pressure, this morning small puddle under right side.
Install coolant system pressure tester, pump it to about 12PSI. No leeeks.
Remove top shroud, fan and bottom shroud.
Lower radiator hose dry.
Lower right corner of the aluminum Champion radiator.

I have used both products, aluma seal and bars leaks before.
Aluma seal i always buy in powder form. Mix about a half of one of those tubes with coolant, thoroughly stir and add to operating temp engine, install cap and run it.
Any opinions on which would be best on this aluminum radiator ?
It does have @Twisted Steel Performance thermal coating applied.
I cant afford to have this truck down any more than what its already been.
Thanks is advance for any opinions.

Mine leaked where the tubes went into the tanks. It got warrantied. Chris was most helpful.

And thats where mine is leaking too.
I think Chris might pop in since I mentioned His business.
If a new bladiator comes I most likely will have Chris give the new one the treatment also too.

But I’m really needing the truck as I’ve got some things to move so I’ll give it the alumaSeal treatment.

Either one is likely to cause damage in the form of plugging up things you don't want plugged up, long term. If you need the truck right away then I would replace the offending part rather than pour either chemical in. Then you can address any potential warranty issues with the leaking part in due time if it qualifies.
