I'm looking for a good adhesive silicone for setting knots.
   I've been using some inexpensive GE and Dap silicone which seems to work good on the deeper set knots. 
   What I'm using isn't working good for a very high set knot, it comes apart in a couple of shaves.
  I don't know if all silicones are created equal and they are all adhesive or some are actually adhesive silicone, difficult to tell on the net info.
     I've even roughed the plug and handle  up with a dremel prior to silicone.

The best silicone sealants say 100% silicone. They will be clear. If you notice, the products are designed to be sealants. They are not designed to be adhesives. They are often used for temporary installation of a knot when there is a potential of the knot being removed to reset the depth of the knot.

I do have a knot that i set in silicone a couple of years ago and it is still holding; I never felt the need to reset it.

If a knot does come loose and you want to reset it permanently, it is best to use a two-part epoxy adhesive designed for marine use. If mixed and applied properly to clean surfaces, epoxy should hold for a lifetime. When resetting a knot, make sure all of the silicone is removed from both the knot and the handle or the joint might fail.

Also got knots  that are set deeper after a couple years no problem.
 I have used plenty of epoxy and other projects not really into that at the moment because I don't want it permanently set.

At Paul's Stubble Daddy recommendation, I have been using Permatex (product number 80050) Clear RTV Silicone. mrdoug informed me that RTV is Room Temperature Vulcanization. This has been working very well for me, and I set some knots really high. I ordered a tube off of Amazon, then discovered the local Autozone had it as well, for a couple of bucks more.

I see this does say adhesive sealant.  I've used some of the red on auto part gaskets probably a different brand high temperature and whatnot. 
     I'm just about messaged Paul to ask about this. Thanks Eric

The Permatex 80050 is exactly what I use. It only takes a small, pea sized amount.

Stubble Daddy  I think no point in private messaging you on this.
   Is that why my silicone didn't stick on the knot that was barely under flush handle, I mean the type of silicone I used?

So the knot didn’t seat all the way down and flush to the bottom of the handle socket or a spacer(s)? That is more likely the issue.

That's a good question . The hole was pretty shallow and I assumed the plug was at the very bottom of the hole. I can double check that with calipers and make sure the hole didn't get to small for it to seat at the bottom.
  Good point Paul maybe it just felt like it bottomed out, I'll check that when I get home tomorrow night.

Here’s a pic of one I set the other day. You can see how the base of the knot is seated all the way down and flush with the bottom of the knot socket:
