WanjaJust repaired a broken Bosch intuvia control unit (the thing for the thumb on the handlebar) It got wet by rain and the contacts on the switches corroded. Now I am searching for a good glue to put the pieces back together watersealed. Any idea?

@rusty379 you could try using a silicone sealant like they use on fish tanks?
@the9thdude thanks for the hint, I am somewhat hesitant to use silicone sealant as glue. But maybe I should just try it. A problem is, that it only comes in big cartridges.
