wow, you must have one heck of a dealer if they are picking the Jeep up and leaving a loaner!
A tire shine will actually work out great on the flares and bumpers. It will or course make them shiny as heck but it will do its job at protecting them. The only thing about that, you will need to treat the flare just like you would a tire. Which means you will need to reapply it everytime you wash the Jeep, etc.
Make sure you dont use the same sponge to wash the flares and the paint once you do put a protectant on the flares, you dont want to get that crap all over your paint.
I use something call Meguiars All Season Dressing. You can get it in the gallon sizes or get a 32oz sample size from AutoDetailingSolutions.com. Its under "detailer line." Most of that stuff in the detailer line is for detailing shop that details alot of cars. Autodetailingsolutions makes it possible for weekend warriors to buy the products by making sample sizes, that way we dont have to buy an entire gallon. Example, the gallon of detailer line Glass cleaner will make 11 gallons of cleaner once you dilute it. I bought the sample size of glass cleaner(concentrate) and can make around 3 gallons. It was only $6 too. The All season dressing is ready to use and is not a concentrate, but the 32oz sample will still last along time.
Here is a Jeep with the plastic cladding of which I use ASD on.

It will last a few washes but the shine will degrade with each wash. If you drive in the rain alot it will wear off fairly fast. You may also notice that it looks like it runs when it rains on it. If you wipe the plastic with a damp MicroFiber towel or cotton towel it will spread it back out.

I buy those blue handled applicators at Advance auto for $1. Makes application alot easier and faster.
Another option is Mother Back to Black. It doesnt have to be used on old plastic, it can be used on plastic that is still in good condition. Ive never used this product but Ive read its good. It can also be bought at walmart.
