Can't say I know much about the 7089 but I do own the 1069s. They are junk, the finish lasted only about a month. I've been able to clean up some of the white oxidation but not all. After months of trying, I'm having a friend paint them.
People may hate me for this but I find ProComp's stuff to be very hit and miss on quality, and forget about customer service you won't find any.
All this being said, I work with two other people who run the 1069(or at least some variation by procomp that looks similar). Neither put a lot of TLC into them, but one set looks pristine almost right out of the box, the other looks just like mine.
Also the Procomp locking nuts I got rusted over in 3 months and the key they gave me had a crack all the way down the side. I was able to obtain a new one for free from the shop I bought it from.
