Found out lens is originally glued. People say you can break the lens trying to remove it.
Does anyone have real life experience and could give some tips? Maybe to heat the lens with a fan etc? But hard glue, likely won't help at all?
Information for others:
It was super easy to unstick the lens. I took a screrwdriver, gently applied it to the lens (I sated with the side that is most outside of the trunk/boot), few movements and it unstuck (the glue is very old). Aftyer that it came of easily (was no need to apply the screwdriver anymore).
10-15 seconds dong it very carefuly
No surprise those lenses fall off sometimes (or easy for thieves to unclip).
Is silicone hermetic supposed to be soft (even 48 hours after application)?
Before using it for my lens I tested by trying to glue 2 plastic forks together.
After 48 hours - it took absolute minimum force to separate them.
And the silicone itself is soft, I assumed it should become rock hard?
Maybe I should use glue instead? I am reluctant as every single person said silicone for this job.
