I've used silicone for 35 years and have never, ever, had a problem with it. Although, true, silicone is extremely difficult to remove (and by that very quality it makes for an extremely good adherent) it can be removed with the appropriate application.
With the appearance of rust on the screw heads, in Ron's photo, it looks to me as if the silicone, in this case, was applied to a wet surface.
It's my opinion that not much is better than silicone when used or removed properly and on the correct material.
