Will I devalue my snorkel hood scoop by painting it black?

My 72 snorkel scoop is in good condition, but it would look perfect with a little reconditioning. I'm thinking along the lines of sanding the imperfections out and adding a coat of satin black paint.

I see them for sale around and don't want to go through the trouble of the restoration if it's going to severely devalue the part.

It looks like it's made from black plastic and cleans up with a little detail spray.
I don't know if it's against the Mopar religion to paint these things or not.

Thanks for any input.
