Hi I recently got a 6061 part that was just machined and bead blasted by another company (very good quality)to be re-bead blasted and anodized. I got them to re blast the part and anodize type 2. Prior the finish was great but it wasn't anodized, now that it's anodized it has patches on it. (They look like news paper texture, or water stains and not uniform dots like prior to bead blast) What reasons would the patches come in, and is it possible to get it fixed? I attached a photo.
Thx
