The paint looks awesome on your car, if I were you, I'd go to walmart or an auto parts store, pick up a mothers or meguiars brand claybar kit, and cleaner paste wax, and learn to clay and wax your whole car, even the door jambs. The. Clean the engine bay with some Simple green and wax all the paint you can find, and use turtle wax brand F21 tire shine on all the black plastics in the engine bay. That shine will dry a matte finish, and not be greasy. This way regular driven dirt and dust won't build up in your bay and keeps it looking new. After a good thorough cleaning, keeping it up afterwards is as easy as a quick rinse and re application. Also, I like using black magic tire wax shine on the tires , it lasts forever.
