Im entering a catfishing tournament this weekend with some big money on the line and while i am pretty confident in my knot tying abilities and have had only a few slip on me since ive learned how to properly tie one. i was thinking of putting superglue on my knots to help strthen them so if by chance i due hook into a monster i have less to worry about.so my question is will the scent of superglue make the catfish steer clear of my bait since they are scent hunters?

I doubt the scent will have any negative impact, may even help.  If you feel the glue will give you a stronger knot there is no reason not to try it. 

I've never superglued my knots for catfish. You're fishing heavy line so just make sure your knot is cinched good with a good pull to test it and you'll be good to go. I'd be worried about the glue possibly causing a chemical burn or something to that effect with my line and weakening it.

What kind of knot on what pound test and line type?

Larger diameter lines do require different knots to be more effective, but glue will not cure a bad knot. 

Use a Uni knot, and your slippage troubles will disappear.

i wouldnt ever super glue a knot. if your knot is going to slip you should be able to figure that out by pulling on it before you ever cast out...

and i havent had a knot slip on me since ive looked up different knots...i was going to put it on as extra insurance mostly

IMO 15-30# mono is about the easiest line to tie a knot.  I do struggle a bit more with thinner mono's and the heavier ones I may tie several times before I'm satisfied.

Good deal- with anything 20# and up I also tighten the tag line with plyers after hand tightened- seems to cinch down just a bit more. 

That should work and the scent shouldnt be a problem

Seldom have I seen a mate on a charter not tighten a knot using this method, either pliers or a fixed object to put the hook around.

I throw glue on my leader knots    Not that i dont trust them i just hate the little bit of braid tag left over sticking up 

Trying to think of this structurally...

 

I'm not sure that superglue would really do much other than bind the outside of the knot.  An epoxy or something that can work its' way into the knot might help, but I doubt it as a knot would break outward, thus blowing a glue or epoxy out.  You would need something with tensile strength, which the line would have more of than any product you could throw at it.
