Help Identifying and Priming/Painting this Material

This wooden shelf is built into the kitchen. I want to paint it since the wood is kind of beat. I don't have any issues with painting the wood. But I do want to paint that yellow backing, but I don't know what it is. I think it's fiber glass, but I don't know for sure. I cannot remove it without disassembling the entire piece. It is kind of smooth and glossy feeling. I figure the oil primer will do fine adhering to it, but I still want to know if that would be okay before putting it on. The solvent may melt it. Does anybody know what it is and how to prime/paint it? I can try to take better pictures if you need. Hopefully you can tell what it is in these shots.

Looks like the acrylic roof panels.

Does it flex any?
If so, I'd only apply latex to it - just make sure it's clean [including cleaner residue]

That is a piece of fiberglass, corrugated roof sheeting. Boats and even their fuel tanks are made from the same materials so oil or water based paints will not harm it. For best adhesion I would lightly sand it to remove the smooth, glossy finish. Or, at the minimum I would give it a thorough cleaning and degreasing with solvent before painting.

The problem with oil base paint is it won't flex any while latex will a little. If the substrate flexes oil base coatings will tend to crack/peel, sooner or later.

Solvent based primers won't hurt the panel.

I'm going to do a test spot with the oil primer just to be sure so the solvent in the primer doesn't harm it. And it does not flex in its current application. It just acts as a wall or divider.

Thanks for the answers.

So, why not just paint the shelving and leave the corrugated material as it is?

To answer that, I don't like yellow.

Sometimes you have to take a step back when presented with a difficult situation and ask yourself, is the end result going to turn out worse than the current situation?

IMO, the end result to trying to paint an unknown material just might fit the above description, But that's just me!

Fiberglass gets painted all the time, as long as decent job of applying the paint is done it will look/preform fine.
