Bill,

I will usually sand clear to 600-1000 wet or dry before polishing if possible, makes the polishing go easier and faster. Proper compounds and proper buffing wheels also make a difference.I have used the clear spray coatings on some things to retain the shine without much maintenance. Just don't use it like paint, real light even coat, I've never tried it in a fuel or chemical environment such as a intake. I would never use a wire brush to polish anything. Wait till you have the wheel grab the piece your buffing and throw it......Go easy and let the wheel do the work.
