best Epoxy

[nevada]

What is the best epoxy for metal ?

doing something different, my 72 had the OEM radio removed years ago, and the opening was cutout bigger to accommodate some 70's aftermarket radio that no longer works.

was going to put a blank out plate on, but acquired a factory correct AM radio but also doesnt work. I placed it in the band saw, cut 90% of the radio off, leaving the chrome face, dial, push buttons.

playing around with using epoxy and face plate to install so truck has the Look of factory radio appearance. I use a blue tooth speaker and phone in truck. New HVAC hoses were bigger than original and there didnt seem to be space to install dead radio and since it is just for looks, didnt mind cutting it up.
What type of epoxy is best to hold radio face and face plate to dash? Thanks
