D600 dust - fixed??

If  you look around on the forums you will see a lot of different opinions. I dont think you are ever going to see "the final true story with solution" on this site or anywhere else for that matter. apparently it is lubricant, not dust. go to amazon and read the most updated verified reviewers take on this matter. I would like a second body to go with my d800 and think the d600 is a good technical camera but I dont want to wet clean the sensor every week. If you dont mind the cleaning you cant bid on one online and get a deal. I would suggest avoiding any seller who says "no returns".
