worst move ever. I'm washing my car, reach for the bottle of Zaino detail spray (Z7??) and instead I pick up simple green. I spray my whole rear quarter panel. It instantly lost its shine and the water on the car stopped beading. I freaked out, washed it off, and re waxed it immediately. At the time, it sure looked like it did some damage, but it definately ate through the wax or zaino I had on the car at the time. everything is fine now. I wouldn't suggest spraying that stuff anywhere near anything important nor would I use it on rubber that often.
