Excellent product! The Gardner Bender Liquid Electrical Tape is easy to apply and dries quickly, forming a durable, waterproof seal. Works great for indoor and outdoor electrical repairs. The black finish looks neat, and the 4 oz bottle lasts long. Highly reliable for insulation—no cracking or peeling. A must-have for DIYers and professionals. 5 stars!

This product works well to prevent shorts or wire corrosion after pricking a wire during diagnostic testing !

Gardner Bender has switched to a plastic lid. It looks like they have no longer have any quality control in Mexico. First bottle of white was semi dried out and lid was not tight. Amazon sent a second bottle and it too was semi dried out and lid was not tight. It is less than a 1/2 full bottle, Solvent evaporated. The black with a metal lid was fine. The black weighed 1.2 ounces more. Problem reported to Amazon support. They might not have any good ones on hand. This problem has been going on all year from the reviews I’ve seen.

Please work with Amazon on a replacement unit. If you have any further questions or issues, I recommend you reach out to our Customer Service Team. 800.624.4320 [email protected] I emailed G B Tech support and this is an excerpt: This failure would be the first complaint we have heard about our liquid tape. And yet Amazon comment on another customer: Gardner Bender Customer Service 3 months ago Hello, Thank you for the information. You should be receiving a full bottle when you make a purchase. Based on your feedback I believe the bottle might've opened a little during shipping. This could've caused it to be thicker and a little dry on the top. If some leaked out this would also explain why the bottle was not full when you received it. If you let Amazon know about this, they will send you a replacement free of charge. If you prefer, you can also reach out to us directly and we'll help you out by sending a replacement as well. [email protected] 800.624.4320 Either the lid is not put on tight or the design of the lid is bad. Shame as when it is good it works better than the other brands I tried. When fresh this has a nice balance between too thick and too thin as some other brands. I had to repair some burnt wires 4 years ago, in my jeep when the bracket came loose and the harness lay against the exhaust manifold. I put on 4 thin coats letting it dry a couple of hours between applications. I just discovered that the harness has disintegrated because of heat and exposed the wires. The liquid tape did their job as the wires are fine. Bottle had a metal lid. Update 2-28-2019 Bottles now have their metal lids back. Product now fine. 4 stars due to big price jump.

Perfect product

The Gardner Bender Liquid Electrical Tape is a fantastic product for anyone needing a reliable way to seal and protect electrical connections. I’ve used this on a few of my outdoor electrical projects, and it works great for keeping moisture and dirt out. The application is super easy – it’s a liquid formula, so you just brush it on with the included applicator, and it forms a tough, waterproof seal once it dries.

When diagnosing electrical issues in cars, I prefer to use a piercing tool to poke through wiring insulation so I can connect a multimeter, test light, or oscilloscope. Some people say you should back-probe the connector and that poking insulation is for hacks, but I've run into plenty of instances when back-probing a connector "fixes" a corroded or intermittent connection. Good luck trying to fix the problem when you can't get it to act up. Piercing the insulation means that you have to seal the hole back up, and that's when liquid electrical tape comes in. A quick dab seals the hole in the insulation. Not too long ago I had to use this to repair an engine wiring harness. The insulation had split on several wires in the harness and the conductors were intermittently touching one another, setting all sorts of trouble codes when the signals shorted. I grabbed the liquid electrical tape because the alternative was to cut, solder, and heat-shrink about a dozen wires in a cramped engine compartment. Instead, I cleaned the wiring harness, dabbed liquid electrical tape over each bare conductor, let it dry, and used wire loom and cable ties to secure the harness and keep it from moving. It's been almost a year and I've had zero problems with the wiring harness. This stuff is a life-saver for quick repairs, especially in difficult-to-reach areas.

Work great used several coats to seal up wire connectors

This product was used to seal a repair to an underground electrical to a telephone cable. It was easy to apply (3 coats, 1 day apart) and, so far, no problems after 2 months. Being bright red it was easy to see what parts had been treated.

Buena calidad

This liquid electric tape is awesome , repairing some electrical issues on a motorcycle, where you cannot get tape without damaging any other electrical components, this is a great product. And there’s alot!!! This will last a long time.

I'd heard of this in a few places and decided to try it with my latest project. I purchased both the Black and the Red for 12V applications. It is fairly odorous so use in a ventilated area. I applied liquid relatively thickly so that it was opaque and it takes a little while to dry. It dried to a fairly flexible coating to stranded copper wire, adheres to silicone, cable nicks, other wire insulation and solder joints well. So far the compound has remained in place and has not torn or begun to peel in a couple weeks. I cannot attest to being a water proof coating, how it would stand up in abrasive locations or longevity so use with common sense.

It does what it says. Magic! Pity there are no instructions... but it really works. You will need a little brush as one in lid is far too big.
