Actually I believe the fins are made of ABS, and no the standard PS glues will not work on ABS. I believe that polyethlene would flex a bit too much and be highly resistant to paint and glue. I think that At, LOC, PML, etc. use PE in their nose cones. CA is a great bonding agent if the joint are not put into shear.
