Hadn't used it in years but use to! Just makes it all shiny and durable feeling.Even hit radiator and heater hoses etc.with it. Try it on your lawnmower or something and see.

Here is a link for 303:

I see it at pretty much all the sporting goods and auto stores. I first started using it on whitewater gear, it has great UV protection. For example, on exterior black plastic on your truck, was it with soap and water, then put 303 on the plastic and it will again have the "new" look. Does the same with the plastic under the hood from my experience.

Good stuff.
Not cheap, though.

It is best to clean your engine when it is cold. The Engine Bright cleaner with a garden hose rinse off is what I use and it works quite well. You will have to wait for the temps to get above freezing though. The 303 stuff really is magic. It is great on your tires and interior plastic and leather as well. My son does auto detailing to make money while he is in college and he put me on to it. He also uses the Engine Bright to do his under hood cleaning. I only use the high pressure spray under the truck and in the wheel wells when things get muddy.

Remember with any degreaser what ever it runs down over will also be DEGREASED. Front axle and all the U-Joints will be subject to a degreasing. I like it clean also, but I have ruined alot of under the hood goodies in my day.
I use rags, elbow grease, and some type of cleaner on the old rag. That is IT. Water is a big *** no no. I had a Chevy one time that I took the hose to and after I was done the wipers worked by themself.
