I tried a few, and so far I'm happiest with
Optimum Instant Detailer. You might search the forums for OID to find reviews, but this is what I wrote on DetailedImage:
I'm glad George recommended this product to me. A light mist wipes away quick, with no streaking problem like other products. I love that it's a concentrate, so a quart makes a gallon - very affordable! My new favorite QD.
