I have just recently been using ultraviolet set resin (like bondic) to attach PE parts with great success. The advantage is you place a little on (I use a toothpick) hold the part in position and use a UV light to set it in a few seconds.
I believe the bond is superior then CA cement in strength and much easier to apply without waiting for it to set up. I bought the resin in a larger container and a 395 nm ultraviolet flashlight each for under $10 on Amazon.
To me this ultraviolet setting resin is significantly easier to use then CA
For attaching PE railing to a ship I still like using Arleens tacky glue, but that to may change when I get more experience.
