Package tray resto

Hi I had planned on just buying a new black package tray for the 70 Duster from year one, till I found out the shipping was more then the tray. So since mines in good shape just faded with a little bit of water spotting, I thought I try and restore it.Any body have any luck painting them, and if so what type of paint did you use. I was thinking of maybe vinyl paint, but I"m not sure, since Its some sort of fiber board.

Any ideas ??
