I just use it as a polish.
On my black car I had, I had to wipe it off immediately to get it off. But on my silver car, I just wiped down the whole car, and let it sit for a few minutes while I cleaned the interior or something, then wiped it all off.
I went back with a wax to seal the polished shine it gave me. Try different methods on a fender or something to see which is best for you.
