Don't know that this answers your question but the paint on Wilson speakers is the same used on high end automobiles. (I think I've heard Ferrari). I use carnuba wax once a year just to shine them up. If there seem to be some irregularities, try a very fine compound and then go to the wax. Just like you would to a fine auto.
