I need to "pin down" the conduit in my wing ribs, and since I don't have any Proseal left, I was considering other stuff I could use for this purpose. In their FAQs, Van's recommends tank sealant or RTV for this purpose. I was discussing this with a friend who was a navy maintainer for many years, and he recalled that years ago RTV was not used on AL because of corrosive properties. A quick internet search found this article http://yarchive.net/chem/silicones.html(from 1997) discussing the corrosive properties of RTV. In a nutshell, it says that silicon sealant formulas have changed over the years, and while the current stuff does release some corrosive agents (acetic acid) during curing, on AL at least, these agents only etch the surface and increase adhesion. It does mention that RTV shouldn't be used on brass or galvanized steel.
Can someone on the list who knows about this stuff help me get a warm/fuzzy that if I squirt some RTV on my wing ribs they won't corrode? Are there any places on the plane where I absolutely should NOT use RTV?
Thanks,
