Loctite 37438 21351 Rear Window Defogger Tab Adhesive, 0.03/0.02 fl. oz.

My rear defrost stopped working. Took it to a shop and the mechanic said gotta replace the rear window. I found this and figured worth a try. Easy to apply and my rear defrost works like new.

This adhesive requires close contact between the tab and surface, the adhesive does not bridge well. If it fails you most likely didn't get a close contact or you moved it while it was curing. Prep is important, clean the surfaces with acetone or alcohol. Practice your technique for attaching and holding for a few minutes. You will need good technique holding it in place while it cures.

I used this to replace an electrical tab that had snapped. This adhesive held the tab well, but only conducted enough current to clear the window a few times. Tested and found the resistance of the joint had increased. *** Instead, use an epoxy with a significant silver content. These are expensive! ***

Very easy to apply

1 year later, Zero issues. Fixed it right the first time.

Needed both rear window defroster tabs put back in place. First used PermaTex. Even after following directions to knead, it was runny and had to be taped into place for 24 hrs to set. It did set up, seems to be holding fine. Not being pleased with the Permatex product, decided to try LocTite which I had to order. Again followed directions, kneading it until correct consistency. Much thicker and applied well. But again it did not adhere within 5 mins as stated on pkg. So it was also taped for 24 hours. It set up a bit faster. Both tabs appear to be staying in place, haven't had to use defroster as yet. Either product will re-set defroster tabs but take your time, expect to tape them into place for at least 24 hours. It will save an expensive trip to mechanic.

Read all the reviews and followed the directions to a T, even as everyone else stated what to do. And it still didnt work.

Reattached wire after the kids pulled it off with this. Our defroster works again. Bonus used blue tape to form a line and used to bridge the gap left by scratch on defrost lines worked like a charm. Still working after 2 seasons.

Fonctionne très bien pour une réparation du dégivreur dans la vitre arrière d’un véhicule. J’ai collé le fil à la vitre et c’a tient depuis déjà 1ans.

اتبعت التعليمات تماما .. نجحت التجربة وتم الصاق القطعة المعدنية مرة اخرى على الزجاج مع ملاحظة اني قمت بازالة اللحام المتبقي و صنفرته ليكون سطح ناعم نوعا ما قبل تركيب القطعة المعدنية... الان مزيل الضباب يعمل والقطعة ملتصقة بشكل ممتاز منذ شهر تقريبا. عيبه الوحيد هو ارتفاع السعر النسبي لاستخدام واحد!!

Purchased on advice of my window repair man. Followed directions closely and allowing drying time. Would not cure/tack and solidify to adhere to rear window.

Expensive, but if you drive in winter conditions without defrosting your windows, well you are a danger on the roads. Just my opinion as a professional driver.

Very good
