best adhesive for plastic to mdf

[SMS 10+ year member]

Im making some removable round port units and need a really strong bond becuase a few of the ports will stick out of the box depending on tuning frequency. the port will probably be bumped around a little in my trunk. i know i should rough up the plastic with some coarse sp where its being glued. thought about makking up some small gussets if needed? it cant be supported on the inside of the box becuase they are interchangable .

thanks for any help

duct tape?

Just make a square of mdf (two layers) a little bigger than the round port and cut a hole through them the exact size or a tiny smaller than the port and you can get it really snug in there and just seal it up real good with some sylicone

thanks, i was just thinking there may be a specific brand that holds the best cause the joint is going to take a little abuse.

1min epoxy, 2 part mix works wonders...
