I searched the archives and couldn't find much on it. I realize a one-step is inferior to a true polish and sealant/wax application, but I have limited time these days and no Porter Cable. I'm looking for something that will add a decent shine, but more importantly protect the paint for a few months.

I have a silver M3, which unfortunately may have to be parked outside starting in a few months (outside all day at work, then outside at a townhome). Hence the concern about protection. Being silver, I don't think it's worth my time to go nuts on the shine.

Anyone used this stuff? I used to do the Klasse AIO and SG, but those were kind of a pain to work with.
