I need your help identifying what material my mushroom panel is made of. It's from a DG-202. Given the age, I'm assuming it is painted fiberglass. But the black pigment runs deep - as if it is really carbon. I'm asking because I'm considering putting the GPS antenna puck under the panel. But if it is carbon, I need to mount it externally. I'm not sure if this is the stock mushroom panel.

its definitely fiber glass. two reasons:

Carbon is more expensive and in a part like this which is non-structural, there is no benefit for incurring the extra cost for the unnecessary stiffness. also, if you zoom in on the pictures, you can see a little green (fiberglass/resin system) where the paint has worn, also the inside of all the drilled holes look white/green (fiberglass/resin system.)
