After an old lens I bought had lens group separation as I thought from the Ebay picture, I disassembled the lens, and took the partly separated lens in the oven at 150°C, and waited ~half an hour. As supposed this worked fine for this lens glued with Canada Balm. For more modern lenses this is more problematic - until now I have found no cheap method without special aggressive solvents.

The now completely separated lenses I could clean with alcohol, and re-glued with a cheap UHU glue for glass. It seems like this glue is a good replacement forlens delamination repair (external link)for hobby tinkerers use.
The glue cures under UV - like the sun.

Now I have no longer the delamination in images with bokeh balls :-)

It is much fun when the repair or modification works well :-)
And it is bad (depending on price and love for the lens) when it did not work well and the lens is damaged.
