Comet,
Not that much different then what we used to call a compound bath. Used ol' Tiger Cut lacquer rubbing compound, Bon Ami, Comet. When you pull your wash mit out the bucket load it with compound and go to scrubbing. Works wonders on a light colored car that's been stained up. Done in 20 minutes and skip the whole compounding step, straight to polishing. It's an old school dealer toss it on the lot trick. It works. I still do it. Works great on fiberglass rv's boats etc.
Don't knock it till you tried it. Great detailing trick that can save a ton of time in the right circumstance.
