The subject pretty much covers it - is the use of this stuff a problem in a hot water closed loop boiler system (baseboards, aluminum exchanger)? I seemed to have dodged the bullet this time, but I was considering using this stuff for a repair. I assumed it was a bad idea, as the location of the repair did not permit flushing it out.
Cheers,
Dave
