but what is the opinion of the group re radiator leak sealant. I have a slight weep on my 2004 Saab and would prefer not to buy a radiator for $400+ just yet. Apparently it is aluminum cored with plastic side tanks like a lot of them are these days. Are there any good brands?
 
I've used ~This stuff~ .

It has worked for me, but like you, I'm not a fan of the stuff.
 
When faced with the same situation... a leak in my car's radiator, I also looked into the "stop leak" products and decided to install a new radiator.
I was not too thrilled about all the little "plugs" that did not seal the leak flowing through the cooling system.
For what it is worth, I bought the new radiator from rock auto for a LOT less than buying locally.
 
I've never been a fan of any stop leak product.
Seen it react in the wrong places, such as heater cores and the like and cause issues after the fact.
And being the Devil's Advocate, it is just a temporary measure anyway.

Bandaid on a real problem - & I don't believe in bandaids....do it right: pull the radiator.
 
Aluma seal is good and won't stop up anything and I favor sodium silicate products. (clear w/ copper particles.)
