Shame you can't stop down and just use the good bit on a mirror lens !

I have a couple of Rodenstock Ysaron (150mm f5.6?) like this. Wondered if we could just add Canada Balsam or any liquid glue (Norland UV-cure) to soak into the air-gap by capillary action ?
Or dis-assemble and re-assemble ?

Taken of what is likely an internal element
separation (the grids of lights are the reflection of the LED
light used for illumination for the photo), even though it looks
like oil on an element. The lens is a rather good 350mm f5.6
Tamron SP mirror lens, although with this problem, it is now
rather soft...
