The new Frost Fighter Grid Repair material features improved electrical properties, better bonding and uses the heat from the defroster to flash cure for fast defroster grid repairs. This is a breakthrough product improvement. Use the new Grid Repair Kit when rear window defroster grid lines stop working. The fine horizontal heating elements on defrosters can be easily damaged by a single scratch or multiple breaks of the heating elements. Repairs are made by masking off and painting the Frost Fighter grid repair conductor over the damaged area. The conductor bonds aggressively, dries quickly, and is color-matched for invisible repairs. New Breakthrough Defroster Grid Repair Technology The new 2120 Grid Repair material is a breakthrough technology featuring a tougher, more conductive repair that self cures in 20 minutes using the heat from the defroster. No more overnight curing! Each kit has 5 grams of repair conductor for up to 35 total inches of repairs using the recommended two coats. This quantity of material allows multiple repairs from a single kit. Repair multiple breaks in the defroster elements up to 3-5 inches in length. To repair a grid just paint on the repair coating, air dry for ten minutes, and then turn on the defroster. The heat from the defroster cures the repair. This is an easy repair you can do yourself and save the high cost of glass replacement. Frost Fighter is a Registered Trademark. Review: Just about perfect! - Save yourself a trip to your car mechanic, because this is the cheapest way to do it, it just takes patience and carefully looking at the instructions. If you look at the very last photo where there isn’t any ice on my car, but a bunch of fog or whatever, you can see that I bought this because several of my defrosting strips were not working; please ignore the pieces of tape. I just put them there. I said I knew where I had to paint on the magnetic defrosting paint. As you can see in the later photos with the little bits of glue left on, it does 100% work if you follow the instructions as well. Now, all of my defrosting strips, except one work, except for one, because so much was damaged that it was hard to paint it on correctly so ignore that one – the product does work. It’s just me that made one not work at the end of the day. If you see the close-up shots from the inside and outside of the car, you can kind of see the brownish color going outside the straight rectangle, because you know we’re gonna paint things on more inaccurately than a machine would when the rear windshield is made in a factory. This process was kind of difficult, because if you have a car like mine, you’ll be painting with the brush, almost vertical, but since paint is liquid, it kind of drips down. Because of that, the only way that I would give it my whole heart backing is if they had some way to hold the paint back while you’re painting instead of having it dripped down to the bottom of the handle while I’m trying to paint, something to fight gravity. They also were nice because they put enough paint in the bottle that I was able to fix quite a large area of defrosting paint, with just one bottle. All I have to say about this product that made me review it highly, was that you really need to follow the manual step by little step, otherwise it probably won’t work. Great product, and please make the brush softer and have a little more paint so it’s easier to make a heavier coat. Review: Have patience it works - Used this on an older car with a few inoperable lines. Definitely skip using the template provided. I used blue tape so i can control the area to be fixed. The template provided is really wide and the "paint" will overlap the line. It took me a few tries on some lines before i got results. It won't be a 100% like brand new but it will be working. What i mean by that, is on the treated line, you may see where the break in the line occurred. Both sides of the line are working , but the place of the break it has a small defrost area due to connection not being 100%. I could probably try and add more to improve, but I got a whole like to work so i'm more than content. ## Features - INVISIBLE GRID REPAIRS: Repair breaks in rear window defroster grids with the Frost Fighter 2120 kit.

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.

I have repaired many defroster lines over the years and it works just as well. The only reason I have it 4 stars and not 5 is because although this stuff isn't cheap, buying it this time the price was very high. ## Frequently Bought Together - Frost Fighter 2120 - Rear Window Defroster/Defogger Grid Repair Kit | Quick and Easy Self Repair Solution for Grid Lines - Frost Fighter Rear Window Defroster/Defogger Tab Bonding Repair Kit 2000 - Frost Fighter Rear Window Defroster Replacement Tab - 2300-URX - Compatible with Ford, Chrysler, Chevrolet --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/59612214-2120-rear-window-defroster-defogger-grid-repair-kit-quick-easy](https://www.desertcart.tn/products/59612214-2120-rear-window-defroster-defogger-grid-repair-kit-quick-easy) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-03*
