radiator stop leak has anyone used any of these products? i used costal last night and it said to let the car idle for 15-30 mins. so after 30 mins there was still steam comming from under the radiator hold down. i belive that these products work by finding the leak when hot and sealing when cooled down? does anyone have any experiance with any product?
All of those radiator stop-leak fixes are temporary and mainly for emergency repairs. You need to replace/repair the radiator if it's leaking. I have successfully sealed up a radiator in an old farm truck years ago with the old egg trick.....got me 15 miles into town to get a replacement.

Lucky. when I bought my Z 2 days later the nipple for the reservoir cracked. I tried to patch it but it didn't work. I told the dealer to come get it and fix it or keep it. The guy put in a new radiator out of his pocket and had it back to me the next day. Never felt luckier, considering the car had 103k miles on it.

I would not depend on that crap at all. All stop leak products are different forms of garbage. You can try using them as a temp. fix but there problem is you don't know when it will give out.
