will this work on a radiator temporarily? has anyone ever used this stuff i hear its pretty good for all kinds of ish

 

As epoxy goes, it GOOD stuff. But the radiator is under pressure so I'd want more than "good" stuff.

I'd be afraid to use it on a radiator for more than a day or 2. When the stuff cures, it becomes a brittle-fracture material for the most part. With little or no warning your repair will blow wide open.

 

There is a product at your local AutoZone stores that goes by the name Liquid Steel..
Clean it, spread it on like glue, let it cure..then you can even sand it , gring it, and paint it ..works great..It becomes a Liquid Steel..I've used it quite often on all kinds of projects...

It depends on the location, on mine I had a leak on the top at the seam and i triedjb weld it held for a few days but it did not hold, like someone stated earlier the radiator is under alot of pressure so this wll probably not last long. I found a radiator for $100 bucks at a local parts store.
