Great Product
The best radiator sealer ever made. This was used for years when rebuilding an engine in the coolant system on start up. To assure the head gaskets sealed. Best stuff ever.

Works well
I have had good luck with this in sealing small radiator seepage. Has been holding for a couple years and no problems with blockage that I have seen. Cheep "fix"!
