well, its just a bit of Acetic Acid (aka vinegar), but honestly, I dont think
Id want something emitting Acetic Acid in a closed space with an aluminized
mirror or optical coatings...
BTW, that Silicone II stuff is also a RTV ("Room Temperature Vulcanizing), its
just one of a multitude of variants of RTV.
from a recent thread on a motorcycle list concerning resealing a ECU (engine
control unit) that was prone to getting water inside...

A comment regarding silicone rubber sealants.
Dow Corning make an RTV sealant specifically intended for electrical/electronic
work. It is designated 738. see:

Though its electrical properties are probably not an issue in the sealing of
enclosures, it is stated to be corrosion free, and in fact also "no
by-products". There's only a very faint odour when uncured. It's main
disadvantage is its relatively long cure time (about 3 hrs to skin).
It maybe a little hard to procure, though any reputable electrical wholesaler
should be able to get a hold of it.
I would recommend this is the way to go for re-sealing your ECU.

and, I suspect this would be good stuff to use inside a scope.
