Follow instructions carefully
Followed the instructions exactly. 24 hours later and rear demister is working again. Excellent product if used correctly.

Failed Despite Following Instructions
This is the second time I’ve tried this product and it’s failed both times. It simply does not bond to the circuit. I’ve followed each step of the instructions to the letter, but when I came to attach the connector the follow day, it came away from the window. Really disappointing.

Works if you follow the instructions
I bought this to re-fix the connector tabs to the rear window demister on a Toyota Aygo hatchback. The instructions are straightforward but very specific about the steps to follow, the amount of adhesive to use, etc. I followed them exactly (eg using only a small drop of adhesive) and the tabs stuck fine. I checked the electrical conductivity after leaving to dry for 24 hours and that's okay too. The only concern I had was that such a small amount of adhesive would provide too little physical strength under normal wear-and-tear on a hatchback window. So once the specialist conductive adhesive had dried I added an additional layer of Gorilla Epoxy adhesive over the top of the tabs and immediate surrounding area of element to form a little "bubble" of adhesive holding the tabs to the surrounding element. This cost a couple of £s extra but makes it a really strong bond that should be permanent.

Expensive for what it is
Expensive for what it is and first kit lasted 2 weeks before I had to order another one and do it again . Thing is there isn’t anything else on the market available.

Didn't work
Followed instructions to the letter. Tab stuck on OK but the glue is not conductive. Very disappointed. Soldered tab on and all works fine.

It actually works
It actually works I seen lots of reviews on this people saying it dont work I decided to try it and it works What I end up doing is sanding the contacts of the defroster terminal that came off the window and on the window it self and clean the contacts where it was mounted on the windshield then use the wipe it give you the activator wipe the contacts and the part on the glass wait 1 min while your doing that mix the solvent until it get like a brownish color then put a couple drops of the on the contacts and hold it onto the window for 2 min or so then let it cure 24 to 48 hours then you can use your back defrost again.
