When you buy the CA, make sure to get the one that is FOAM SAFE, and get the thicker GAP FILLING one if you can. Put the CA on one piece, spray the surface of the other piece with the kicker, then join them together. You will have about 20 seconds to get everything lined up, then hold the pparts together for one minute. Repair is done.

You can also use 5 minute epoxy, and for some repairs clear packing tape works best.
