Can you use on wires and electrical

No. Either use tin/solder for electrically conductive metals or an epoxy for non-conductive metals.

Would it work on an oil pan that has a small leak between gasket and block without taking pan of again Only leak when running

Doubtful super glue will work. The seam between the oil pan and engine block will be heavily soiled with oil, grease and dirt. And, if the leak is only occurring while the engine is running, possible there's a small amount of pressure and/venting occurring at the weakening of the gasket. Better time spent, working on the proper solution. Either buy the vehicle's de facto repair/service book/manual, gather some tools or contact several repair/service shops. The least you can do, in order to ensure the repair shop easily finds the leak, clean the specific area with some mineral spirits or WD-40, careful of any plastic or painted parts. If well painted or plastic, use Dawn dish soap for cleaning the area, and rinse. Bottom line, I wouldn't waste any time on any epoxies or oil additives, as those speculative solutions only serve to compound the problem

Will this work for a car rear view mirror back to the glass?

Yes !, First you need to clean the surface of the Window that the 'Mirror' is to be attached to with Paper Towels wet with '91% Alcohol' as while as the part of the 'Mirror' that is to be attached to the Window. If possible remove the 'Mirror' from the part that is to be attached to the Window, this will relieve or decrease the weight of the 'Mirror' allowing the part that it is attached to the 'Window' to be 'Taped in place with 'Duck Tape' to allow it to 'Dry' without Holding. ( allow to dry for 30 to 45 minutes ). Once dry, reattach the Mirror to the Piece. It should remain in place for months or a few years !. ( Depending on the Climate !.)

Yes !, J-B works practically on any material. Before applying it to your Aluminum surface, clean & wipe area with a paper towel moistened with a 91% or more percentage of Alcohol. (Allow glue to set & dry for 30 minutes to an hour.)

New go-to glue.

Love this stuff. Works on seemingly everything; wood, plastic, those little angle figurines that get their heads knocked off, glasses, etc. it does take a full 30-60 secs of pressure between pieces to adhere but then holds very well

Versatile glue.

It can be used in home, and I also used it to fix the wiring for my car dashcam. Hasn't fallen off so far.

Poor Sales Tactics!

Glue = 5 stars Amazons Nonsense = 0 Stars To explain, I didn't realize at the time that one tube was $5.97 yet two tubes was $16.28 . I could have bought three single tubes for not much more than the two pack. Don't make the same stupid mistake I did! Glue works great tho
