Final answer:
Sealants should not be applied to metal that is colder than the dew point temperature.
Step-by-step explanation:
Sealants should not be applied to metal that is colder than dew point temperature. The dew point temperature is the temperature at which dew forms when air is cooled. When a metal surface is colder than the dew point temperature, moisture can condense on the surface, preventing proper bonding of the sealant.
