Air Powder Polishing

TODAY WE DID AIR POWDER POLISHING. IT WAS SOMETHING I HAVE NEVER SEEN BEFORE, AND HAVE NEVER HEARD OF. IT WAS REALLY MESSY, AND TASTED SALTY, BUT SEEMED TO BE VERY EFFECTIVE. IT WAS COOL TO DO IT ON A DIRTY OLD PENNY AND SEE HOW MUCH GRIME WAS REMOVED. I ALSO PASSED OFF MY UNIVERSAL POSTERIOR SCALING PE TODAY SO I AM HAPPY ABOUT THAT
