I don't trust any new waxes as waxes and wax companies go out of business as quickly as they pop up. Also look at the types of claims wax companies in the past have made with setting hoods on fire, shooting lazer beams at it and throwing sand and mud on the car, non of it realistic, just marketing scam. Teflon wax falls into the too good to be true catagory.
I stay with the well known products from Klasse, Meguiars, Eagle, Zaino. The wax that's really been working great for me now is Meguairs NXT, better than Zaino and Klasse. It's easy on/off and clear so you don't get the white powder. I clayed and waxed my 2004 in November and when I went to re-apply in March it was still very smooth. I bought some Eagle Nano Wax but haven't had a chance to try it yet.
As for tires turning brown, that's normal, they release a chemical as you drive to keep the rubber from drying out. I use Eagle Tire/Wheel cleaner and clean the tire the same time I clean the wheel and it washes the brown off. Do that before putting on any tire dressing products.
