blacklimitedcoupe...303 Aerospace protectant is a pro detailer's favorite. I have just started to use it on tires, and it last much longer than my Autogylm tyre dressing, but the shine is not as greasy...instead it is a very natural look. Keep in mind the 303 stuff is I believe water-based, meaning it will not fade your plastics like silicone-based dressings. Try the stuff on plastics too. Meguire's #40 for plastics works well too...A very versatile product that I use for interior cleaning and all rubber and vinyl surfaces as well. The meg's #40 is really a time saver because it has cleaners, conditioners, AND UV protection all in one product. It has saved me at least an hour on details! Lastly, try the 303 on the engine bay too! Good luck with your detailing pursuits and keep on asking if necessary as I know there are at least a few on this forum who truly know their stuff!
