I guess after 6 years of spraying WD40 on the gun enough of it got on the scope to eventually effect the protective coating on the scope. What is funny though is even the rubber grip ring for the front AO and magnifier ring had the same gunk on it. I guess that is what can happen with a mat finish.
I've got 2 old Redfield Trackers that are gloss painted and they've been sprayed with WD40 for more than 25 years. I hate like hell to take that scope off. It really is/has been a good one.
One thing you have to watch with WD40 is that it is silicone based that silicone and metal creat rust also it melts rubber over a period of time so I would never put that stuff near anything like that, if you want to remove it use something like methalated spirit and with a cloth just wipe it off, and if you want to try and restore the rubber parts go to a plumbing store and get some white/CLEAR rubber or Plumbers grease, rub it well in and wipe off the excess properly and that will help, the Grease that tasco use does come out of their products from time to time due to tempreture and old age so put it in a place to warm up before you try to move any moving parts and then wipe off the excess and if you want to put anything on them use that Rubber grease and wipe off the excess again that should keep it good for years, Also use that grease for any rubber armoured scopes and gear you have because it is a rubber lubricant and it will prevent the rubber armour from cracking, My scope still looks like new after 16/17 years and I would not sell it for the world,
hope this helps
