Block crack

Same as Moroso ceramic seal. Red label, Blue label was for use with antifreeze, but not as effective. Used it a few times.

Will liquid glass fix a cracked block?


Description. The original Liquid Glass Metallic Seal-Up. Seal-Up liquid glass metallic formula will seal cracks permanently. Works excellent on sealing engine blocks, radiators, heater cores and freeze plugs.

I have used K-Seal with great results for Dodge heater core leaks also. Saved me an $800-$1200 repair bill.
