CA Glue On Tube Ends?

Some builders get carried away with CA Glue (Super Glue) reinforcement of body tube ends.

I've seen a forum post where the builder was letting the CA glue run down inside the tube. He was doing his best to see the entire interior was coated.
CA Glue can stiffen up the edges of body tubes, but there's no real need to apply it any farther down than 1/8" to 3/16" or so.

While the CA glue will harden up the tube end, it probably won't stop a Kevlar zipper.
