Here's the problems with any epoxy (yes, "Liquid Steel" is an epoxy)...

First, heat expansion...
These epoxies do not expand and contract like the surrounding metal.
Due to the heat cycling of the metal (i.e. aluminum), the epoxy will eventually work itself loose due to the heat cycling.

Second, how does the epoxy react with the coolant?
A lot of them do not like being immersed in chemicals.
You need to confirm with the manufacturer that it is okay to be "submerged" with your coolant.
Most epoxies do not like to be in contact with glycol based liquids and will eventually erode away.
