Which part are you talking about. If its somthing like an IP, i would use white glue. If somthing else whereyou are just gluing a thin edge, i would use CA.

White glue will hold PE?  I thought that was only for styrene or will the Testors stuff that is used clear parts work?  I also have the Arleen's tacky glue, just curious will that work as well

I use wood glue. If the testors stuff is the same as the Microscale 0ne for canopy's, then ye, that will work. And if it is for an IP, the good thin is you can cover the whole back piece and when dry you will have clear lenses on the instruments.

White glue is fine for gluing small PE pieces to the model.  The weight of the PE pieces are so light that not a lot of strength is required.  However, as someone above mentioned, I would not use white glue to fasten a piece of PE edgewise to another piece of PE.  A week bond with not much area could result in that piece coming loose and disappearing.  For gluing PE brass or stainless to another piece of same material, CA is about the best.  I think gel CA might be a bit better in this case, because you can make a fillet at the joint which will add strength.

 And for gluing a PE piece to a painted PE piece, make sure to remove any paint at joint area first. In fact, I would glue pieces together and then brush-paint.
