Yes, you can see corrosion on metal parts from acetic acid based RTV curing. The acetic acid would attack the solder, and any exposed copper; you can see the color change. You can get sensor-safe RTV sealant that do not use acetic acid, like Permtex Blue. Or, if you don't have that handy, you can flow solder over the bare copper to protect it from the small amounts of acid released during the curing process, like I did.
When I was at Ford, I noticed that all the boards in the EEC computers are coated with some kind of silicone rubber. They must use some kind of dipping/baking process (not RTV). That was kind of my motivation for using silicone rubber.
I've had good success using the non acetic acid RTV on electrical connections especially for the boats. electrical and marine parts stores carry the non corrosive RTV that has extra adhesive properties.
also use the melt seal lined heat shrink.
neither are not fun to have to peel off for redo but they do seal out the salt water corrosion well.
I like the non corrosive RTV for exposed nut and open connections that can't be heat shrinked. used to use thick grease until I got onto the electrical grade RTV, grease is messy.
