500SEL A/C Compressor Part Deux!

After having problems with the A/C compressor shutting down all summer I finally had the serpentine belt and tensioner replaced. The A/C ran great for 5 days then quit. Out of desperation I took Peter Guenther's suggestion and sprayed belt dressing on the belt and VOILA! It worked!

Yesterday on my way home from Mass the darned thing quit again. I again sprayed the belt dressing on, restarted the car and the A/C worked fine.

My question is- should I plan on just spraying belt dressing on every month or so or is there something that I'm missing? The belt and tensioner were replaced by my indy mechanic, but were directly from the MB dealer.
