TL;DR -- Product works incredibly fast and well. Use in the shade, well ventilated area. Wear gloves.
Review:
As several others have stated, it does smell bad. When you read reviews online that say something smells bad, normally you take it with a grain of salt. Like I said to a friend, it smells like you've blended two-part epoxy together, smeared it on the inside of a full-face motorcycle helmet and put said helmet on. It's strong. VERY VERY strong. The "cherry" smell is there, but again, don't sniff this stuff. Don't use it in an enclosed space.
As for the product itself, it works incredibly well. In the shade, I'd spray a quarter of the car, let it sit for a minute or so, then begin wiping down followed by a thorough rinse before moving onto the next section. (I'd do the complete rear bumper and trunk lid as one part. Then the drivers side doors and rear fender as one part. Passenger side doors and rear fenders. Roof. Front fenders and hood. Front bumper)
I strongly recommend wearing disposable gloves when applying the product, as well as when you are scrubbing/wiping.
Product is very easy to rinse off after wiping. Might have to apply two times if area is heavy soiled with contaminants. Followed up immediately with a full claybar (which took no time at all), polish and wax.
