I am looking to shine up the trunk fairing and all of the plastic stuff that is not painted.
I been happy with Armor-all type products. I have something by Black Magic I bought years ago. Its a silicone type oil/cleaner. I use it on all the plastic inside the engine compartment of my truck. It cleans it and shines it up all nice. Last awhile inside there. Should work for you. Its slippery when it gets on your hands.
