Which Adhesive to Re-attach Tank Heater Pad?

The leading edge of my gray tank heating pad partially detached on the final leg of our trip home. It's hanging approximately half off (just enough to rest on my driveway). Looks like the original attachment was a "peel-&-stick" method.



The front edge looks good, so it didn't drag on the roadway. But it probably bent completely backward (flapping in the wind) so I can only hope the wiring is ok.


Anyway, I need to re-attach so any suggestions are appreciated.

I cleaned the surfaces with denatured alcohol and then used contact cement.

Thanks. Did you have to take the old adhesive off, and if so, what did you use?

I'd just use that ol' yellow automotive contact cement.

You can use 3M spray glue found at hardware stores. Good stuff.

I cleaned with solvent then used liquid nails and held it for a few hours with a piece or wood jammed against it. Has worked fine for a year and thousands of miles.

Yes, I thought about using Gorilla Tape around the perimeter after reattaching just to keep the edges secure.


Thanks for all the suggestions.

Heating Pad Adhesive

In Alaska, we used the high-temperature RTV silicone adhesive for pad heaters on oil pans and transmissions. (Red color) It is available in automotive supply stores. Self-adhesive aluminum tape was placed over the pad to protect the heater from road debris/salt etc. Just be sure to clean the surface thoroughly before applying the adhesive.



My heaters are still firmly on and functional after ten years and 100K+ miles.



Good luck!

+1 even though have not used yet on my AI pad heaters, but I have used on plenty enough areas in the underbelly of my other vehicles (mostly oil pans and trans), that I can definitely say they work.

I'd also recommend 3M Weatherstripping Adhesive (sometimes called "monkey snot").




Clean the surfaces well. Follow the instructions.

I strongly agree with this guy!!! I worked with heavy trucks in Alaska for years and this was always the best way to attach something like that. Take a can of Brake Clean to clean the surfaces and apply the RTV generously. Make sure to let it cure for at least twelve hours before driving. A day would be even better. Itís not going to fall off!!!! Motor On!!!!
