If the window tint is covering the grille, it may have to be removed because you want the liquid to make contact with the metal grille. Then I would check the connectivity (where I patched it) for continuity with a multimeter to make sure there is a good connection where I fixed the break in the grille. **Q: One of my grid tabs fell off. Can this be used to build up a postage stamp sized area where tab was is thin to bare? Cab the tab be put onto the area?** A: Thank you for the question on re-attaching a broken tab of a rear window defroster. Here is what to do. When defroster tabs come off the defroster it is common some of the defroster can be pulled off the surface of the glass. The 2000 Frost Fighter Tab Bonding kit can rebuild this missing defoster and bond the tab back to the defroster is a single operation. This is an easy repair you can do yourself. Start with the 2000 Frost Fighter Defroster Tab Bonding Kit. Mask off an area around the damaged area on the defroster using any masking tape. Mix and apply the highly conductive silver bonding adhesive inside the masked off area and then a little to the base of the tab. Remove the masking tape and you will have a nice pad of conductive adhesive covering the damaged area. Place the tab in position on the wet 2000 tab bonding adhesive and cure as per the instructions.
