I wanted saffron yellow and that color was the best one I could find.
The side panels are 16mm (0.63 inch) and the rest is 10mm (0.39 inch).
I'm sorry but I don't know the name of type of the paint/primer in english (google translates to "aqueous acrylic enamel").
The black is spray can paint, smells pretty bad and it's a PIA to apply. I used it for the marquee aluminium supports, control panel and the monitor bezel.

Sanding is very important, especially on the cut edges, because it helps seal the MDF.
I think I applied 2/3 coats of primer and 2 coats of paint.
