If you need the inner surface black, bunnings have rolls of black self adhesive felt in the aisle with surface protectors, used for draw liners as well. Sticks well to plastic and doesnt reflect much. I’ve added a picture of the jacket I made. The black is the self adhesive felt used to reinforce cut edges. Didnt need to cover the lot because I have a separate dew/stop annoying streetlight shield which is lined with the felt.
