Try Silkolene Pro prep to finish off the engine compartment. I promise you won't be disappointed... makes plastic, rubber, etc look brand new. I discovered it years ago when I was doing motocross. Made the beat up scratched plastic on my bike look new again and it puts a protective film on everything. Started using it on everything... even interior plastic. You can spray it on and leave it or wipe it down
