Heres what I do. I go to the quarter wash and use the "engine degreaser" and spray it all over the engine and then rinse off. If your car is real bad you may have to use the entire cycle of degreaser and then another cycle to rinse. After you do that go and drive the car for a bit to help dry everything off and go home to dry off the rest. Then what I use is the foaming tire shine and spray it everywhere, let it dry and you may have to wash your car as the foaming tire shine is coming out of an aerosol can and gets everywhere. You can minimize this by doing it in the garage but who cares if it gets on the car, just gives you reason to wash the car anyways
As far as the brand of tire foam I use the cheapest stuff because I don't see the difference but if you use the stuff thats not foaming but comes out of a can, like Black Magic, it seems to go on thicker and I think it would last longer, even after you go and wash it again at a later date, good luck with your car and post some pics
