there was a thread about the radiator stop leak a few months back. I think the bottom line is that it is best to fix the problem correctly with a new rad. Rock auto has them for about $100. the additives will stop the leak but they also will clog up other parts of the engine and heater core. however it does come down to time and money and you would not be the first person to use the additives. I used the little aluminum flakes one on a f150 and it worked and the truck had no side effects from it for the 2 years i had it after wards

My radiator is currently leaking too, I've ran the stop leak stuff and it worked for a couple of weeks but the leak came back. Right now I'm in no position to buy a new radiator, so I just make sure the level stays topped off. With winter coming up it wont be a real problem, I'll probably wait till the summer to fix it.

First I used some cheap parts store brand, then I tried the bars with the aluminum flakes. Both worked for a little while, but it is leaking again. It's a real slow leak, I only have to top it off once every week. With the cooler weather I'm not too worried about it right now.

I bought some aluminum rods a while back from someone at an auto flea market. he was fixing old rads and stuff at the fair. he used a torch and the rods. i am not sure how well it works but thought i would mention it.

Hmm, aluminum brazing. I have heard of it but never tried it. Maybe if I get really bored sometime I'll give it a shot.

I've successfully used "Alumaseal" as directed, without plugging up the radiator, or heater core.

additives in the coolant don't go to the leak because they don't know where the leak is. They go where physics tell them to go. They don't solve the problem. They create another problem. That problem being; they are foreign additives in your cooling system.
Either fix the orginal problem or don't. Don't create another problem.
