You pose this question in the antifreeze capital of the world?
More seriously, stop leak products are best for pinhole leaks in things like the radiator fins. It's not going to end a gasket leak. The chemistry that bonds the stop leak to pinhole leaks isn't even compatible with the material that's failing in the gasket [like putting a band-aid on a broken bone. Band-aids fix skin abrasions]. You're gonna want to replace that.
