Looks like they're suggesting what appears to be an oxidizing paint sealant, per Amazon: "as soon as the contents are exposed to oxygen, the hybrid polymers immediately begin to cross-link and harden"

As such, if there's an issue with moisture infiltration into the sensor assembly, this should help. That would correlate with my experience that it's not cold, per se, that result in the IA failure to unlock (mine malfunctions by repeatedly locking the doors when activated).

 

Have fun,
