Been awhile but have done a good bit more!
After a lot of scraping with a razor and soapy water... clean glass!!
In order to make the bezel sit snugly behind the control panel, I had to add an extra 1cm to the back of the top panel and trim it to an angle. I did this with wood filler, a knife and a lot of sanding!
I then applied the vinyl overlay to the control panel and cut out holes for the buttons and joystick bolts.
The cabinet is now finally inside, cleaned (it was verrry dirty) and paited!

Next... installing control panel, bezel, marquee and t-moulding!
