Plastic glue - what to hold controller ports to cutout holes

[chillywilly]

I dremeled out some holes in my project to slide nes controller ports into from behind, whats the best glue to hold the plastic together?
mind you now there is going to be a lot of pushing in of the controllers so its gotta hold

also my dremeling wasnt too accurate, whats the best thing to fill in the gaps around the ports

and what should i cover the front of the port with so i dont get the glue/paint inside the post holes while im holding it together and making it look pretty

thanks in advance

I've been using Loctite's Plastic Epoxy. Stuff's pretty durable.
