How To Repair Window Defogger Strip:

Put the measuring lead (Red) and the reference (Black) of the Multimeter on the damaged grid line at both ends, right where the grid connects with the wide bus bars. Move one probe--it doesn't matter which--to the center of the line. If you now read 6 volts, the scratch is not in between the two probes. If you read the same system voltage, 12 volts or so, the break is in between the old probe location and the new one. Just move the probes until you find the location that has full system voltage spanning it. Now it's time to turn off the de¬froster grid and the ignition switch.

How To Repair The Defroster Tab:

  1. Clean the tab and the contact area with the alcohol prep. Then apply activator to both surfaces and let it dry.
  2. Apply the completely mixed adhesive kit to the prepared surfaces, and gently press these surfaces together. Contact pressure is adequate for strong, reliable bonds; however, maintain contact until adhesive is completely cured.
  3. Press the tab onto the contact area. Use masking tape to keep all parts held in place asit takes 24 hours at 50F or higher to dry. If the temperature is lower than 50F, then wait 48 hours. Please wait 24 to 48 hours before usingthe defogger.

Defroster TABS:

The tabs located along the sides of the defroster connect the defroster electrically to the vehicles defrost circuit. One tab is the positive and the other ground. If a tab comes off the defroster this will mean total instantaneous failure of the defroster.

  3. Some separation of components is common during shipping and storage. For this reason, it is recommended that the contents of the shipping container be thoroughly mixed prior to use.
  4. Some ingredients in this formulation provided may crystallize when subjected to low temperature storage. A gentle warming cycle of 52°C for 30 minutes prior to mixing components may be necessary. Crystallized epoxy components do not react as well as liquid components and should be re-dissolved prior to use for best results.
