whats the best thing to use to smooth out the knot? superglue?

I don't undestand your need to "smooth out" your knot.  If you tied a bad knot, retie it.

just to make slide thru the guidessmoother.ive heard of people using glue.

Could be your knot. I use an albright knot for braid to flouro. A dab of super glue (Many say you don't need it. Its more of a psycological thing for me)and cut the tags tight to the knot. If tied and snugged up properly you won't have an issue with it getting hung up in the guides.

I agree the Albright is the best, most easily tied, of the compact leader to line knots, but even it can be noisy going through the guides.  Some of it is the length of the leader; experiment to see what works best with your setup.  Some say that having the knot just onto the spool works best, and that seems consistent with my experience.

There are a few knot glues out there. I think they are used for salt fly outfits to make sure the line to backing knot goes through the guides as well as possible.  And I've heard a lot of guys use super glue.

One thing to keep in mind, if you have a knot going through the guides, sooner or later it will get damaged.  Check it now and then, and rety now and then.
