Looks like the product has a 2 year shelf life (if unopened). Then a 6 month shelf life once it has been opened. For those that don't have an immediate use for this.

Vinyl electrical tape isn't really waterproof. There is special waterproof tape, but it's a not easy to use.

Anywhere you would use heatshrink tubing, but can't apply the heat needed.

From the product page:

- Weatherproof protectant for wiring and electrical connections
- Goes on as a liquid and dries to a flexible vinyl polymer
- Resists dirt, dust, chemicals, and moisture, ensuring that connections stay intact
- Brush top applicator allows coverage without gaps
- Suggested Applications: Ignition Wires, Underground Wiring, Outdoor Lighting Fixtures, Bilge Pumps, Terminal Blocks, Exposed Wires

Although, not sure why you would just use electrical tape for all of those applications mentioned. Unless it's a tight spot with no wiggle room, but tape is thin so not really sure.

This stuff is like $11-$12 at the local auto parts stores.

Anybody used this? How does it compare to 3M Super 88 tape, especially for outdoor use?

Might get a can at this price, and put it on the shelf for the future. Love the Permatex products, so might give it a try.

I plan to apply it to the wiring ends on my 21 year old car. I have some cables and harnesses that had the electrical tape or sleeves basically break apart prior to my ownership. Small areas like the connector for a O2 sensor, headlight bulb harness, etc. I can see the colored wires exposed to the elements and get concerned since they're such small components.

I also recently damaged my extension cord's outer jacket, the wires inside are intact, but the electrical tape holds on to dirt and rolls/peels so I have to replace it after every use. I plan to apply this stuff on the cut and hopefully be done with it.

It has a relatively high dielectric constant (like over 1000V per mil) so thickness wise it can sustain higher voltage than electric tape in tighter spaces. Also in tight spaces you only need to hit the short/exposure, with tape you need to hope you get it around the entire perimeter/circumference and it stays there long term. Make sure you mix it thoroughly prior to every use and keep in a stable room temperature when storing.

I use it for LV wiring all the time if you nick a cat cable or say data/LV wire into HVAC and I will use it for 120V/230V applications where needed. I personally won't use it above 120V because uniformity matters, but any low voltage/waterproof/moisture this stuff it the boss. Since it is waterproof if you want a professional look thereafter you can use shrink tubing for a finished look. You can also slather it in terminal blocks to prevent shorts where you have like 3+ wires in a terminal, and in auto/marine applications this stuff is the boss. I will bond with inline wago or this.

This also has UV resistance, so it can withstand outdoor, however I normally put another layer over it for secondary protection to increase longevity if there is a lot of sun on it.

Since I have started using wago and this electrical tape is for secondary protection only and wire nuts are gone. I have shifted to terminal crimps also where possible.

To me: wago/inline, terminal crimps, liquid tape is the trinity of modern electrical.

I used it to modify a new sump pump allowing it to use a better float mechanism. I encased two wire nuts. It's been underwater for 18 months with no issues.

I also used it to repair a 100 foot 12 awg extension cord that had rodent damage.

Both applications required 3 applications applied 30 minutes apart per instructions to achieve sufficient thickness. After applying I waited 24 hours for complete cure.

Appears to be dead as price shown for me was $11.55. They have it in a 4pk where the breakdown would be $5.94 each but very few people would ever have a need for 6 bottles with a 2 yr shelf life.

Could it be used to fix all those apple cables that fray at the ends? Its often hard to push a heat shrink thru fat connector (magnetic connector for older macbooks) and I am thinking this liquid may work

When you nick a wire and won't/can't pull a new one.

6 months goes by quick…..especially if you have winters and the garage is a ghost town for 4 months….. thanks for the info.
