Use these quick fix sealants only if you are trying to get a little more life out of a vehicle before you are ready to get rid of it. It’s not a real fix long term and will eventually migrate through cooling system causing additional issues such as overheating.

Should anyone want to try a sealer like this, by-pass your heater core first, or you will likely clog the heater core.
