HI,
I generally use self adhesive foams or super glue when replacing the light seals.
Recentgly, I am thinking to switch to "gorilla glue".
Is it suitable for the job?
Thanks up front, |

Gorilla glue, as far as I know, is a polyuerathane (spelling?) adhesive. I have used similar products.
It has the advantage of bonding just about anything to anything, but I do know that some syrofoam products are not suitable for these types of glues (you would have to test it).
I think that this type of glue is a bit much for light seals. It is not the easiest substance to clean-up, so you would have to be very careful with it. Also, it expands as it cures, so if you put too much glue in one spot it may ooze out onto another surface.
Once it is dry, it becomes rock hard and can only be removed mechanically (scrapping or chipping). I wouldn't want to be the next person to have to replace light seals that have been glued with that stuff!
I'm sure it would work, but you would have to be very careful. I would look for a more forgiving adhesive. |

I agree with Waynemel. In addition, it is moisture activated in that some moisture is required. On wood, lightly wiping one surface with a damp paper towel is enough, but I think its foaming/expansive characteristic would pose a real potential mess.
Honestly, I think it is the last adhesive I would consider for that application.
If you ever had to replace the seal again, you may need an air chisel or grinding wheels to get the old stuff out.  |

I've used Gorilla glue for camera work, but would never use it for light seals, for the reasons specified above and because I would worry about it expanding into the seal material and making it rock hard and non-functional. I only use it for things like laminating wood to make lens boards, putting wooden pinhole camera bodies together and etcetera. |
