Q: Does ACDelco Cooling Coil Coating have a shelf life?
A: Yes, the 4 oz. bottle has a shelf life of 5 years.

Q: Does ACDelco Cooling Coil Coating contain any perfumes or fragrances?
A: No, ammonia is incorporated into the product for emulsification purposes. When ACDelco Air Conditioning Cooling Coil Coating is being installed, you may smell the ammonia. However, once the coating has properly dried and cured, it gives off no odor or fragrance.

Q: Will ACDelco Cooling Coil Coating cure properly in unheated air?
A: Yes, though the water and ammonia used in ACDelco Cooling Coil Coating evaporates faster when heat is used in the drying process. However, even without heat, the product will dry and cure. In ambient temperatures of 70 degrees Fahrenheit/20 degrees Celsius and low humidity (less than 50%) the product can be cured in an airstream in approximately three hours.

Q: Is it necessary to clean the evaporator before applying ACDelco Cooling Coil Coating?
A: Yes, it is recommended to use the product on as clean a surface as possible. However, advance cleaning is only necessary if there is substantial contamination visible on the evaporator surface.

Q: Will ACDelco Cooling Coil Coating still be effective if the evaporator is not dry?
A: No, you MUST dry the evaporator at least 20-30 minutes before you apply Cooling Coil Coating. Similar to paint, the coating cannot adhere to wet surfaces. It must be applied only to dry surfaces.

Q: Is the aerosol can system as effective as the more expensive liquid supplied with the kit?
A: The liquid system, when applied correctly using the applicator kit, has been found to be much more effective in eliminating A/C system odors when compared to the aerosol can method.
