ONE OF THE SURFACES ON A 6061-T6 SQUARE BLOCK GETS POLISHED TO A MIRROR FINISH BEFORE HARDCOATING. WE DO NOT GET THE SAME HARDCOAT THICKNESS ON THE POLISHED SURFACE THAT WE GET ON THE REST OF THE PART. FIVE SIDES WILL HAVE .002 THICKNESS AND THE POLISHED SURFACE WILL ONLY HAVE .0012 THICKNESS. IS THIS COMMON OR IS THIS THE FAULT FAULT OF THE ANODIZER?
