OK, now I am just plain confused...
I have our 1976 25' TradeWind all gutted and the shell off the frame. Currently I am working on some tasks related to the shell. I have removed all of the cast aluminum Airstream letters from the front and back as well as all of the emblems and they are refinished awaiting reinstallation. Here is where my confusion begins.
First, let me say that I have read many threads dealing with sealants and the "sealant summary" is very concise and helpful, however I have not found specifics for the situation I describe below. I have a few questions regarding specific sealants and techniques and I only want to do this once, and correctly, the first time.
What is the sealant that was originally used on the inside of the skin--the white stuff that never hardens which is found on panel seams, ribs, around windows...? What is the equivalent product to use today? I am looking for the specific product as the terms "Vulkem", "Trempro", etc do not provide enough information to obtain the appropriate product or variation. As an example, I have some new Vulkem 116, in aluminum color, however it says not approved for interior use, so I do not think I want it between the walls of the Airstream, although to use it over the exterior window eyebrows seems like it may be the right product. So, what is the correct, safe, product to use with confidence--one of the Trempro variations: 626, 635, 636? Or is it something else? What about the Loctite product, PS 40, I believe?
What is the appropriate sealant to use around the studs of these cast aluminum pieces before refastening through the exterior skin? Also, where can one obtain the nuts used to fasten these letters and emblems--the small nuts with the rubber washers built into the nut? I also need to reattach the "hanging strip/hinge" for the front window shade/protector, and install the running/clearance lights--would you use the same sealant when reattaching these with pop rivets and screws respectively?
Thanks in advance for any guidance that can be offered!
