  1. One note... The AC Delco is an anaerobic sealant, which is made to seal precision machined surfaces, like transmission cases. To see it's true capability, you need to test it with a precision machined surface. That's why it's a thin gel, so it can seep into microscopic scratches to prevent leakage. Also, it only harden in the absence of air (hence the name, anaerobic), which is the condition is machined surfaces.

  3.  @idontno0  I AM an old timer. I know the difference between RTV and anaerobic sealants. Been doing this for 35 years.

  4. I used to use Nissan RTV Grey because I worked at Nissan. I believe it was made by Permatex, so now I use that at my shop. The only time I've had cars come back with a leak, it was technician error by not thoroughly cleaning the mating surfaces. I use alcohol pads to prep the surface after cleaning.
