Sorry wikd I will have to disagree with you there. I still respect your input though. Bars stop leak is bad very bad! Those aluminum pellets actually do more harm than good, they actually plug up the heater core, and it is a motherfuc$er replacing the heater core.
Use regular house hold pepper a couple table spoons, it will work it's way to the leak and seal it temporarily until you can fix the problem. Pepper is easy to flush out also that bars stop leak doesn't flush and reduces the size of coolant passages within the block, can actually raise the temprature of the engine if you use to much of it.....
Just my 2cen't from a couple years of driften hard.......

 

i agree with you on the bars... it is a cheap alternitive for people who cant afford other ways of fixing... i would use liquid glass if i had the choice... the copper in it will only bond to copper... radiator welds and heater core... and in most cases the lead in the head gaskets... it wont bond to any of the rubber lines or the steel lines in the car...
