Sealant types and uses

Ok, I've read numerous threads about sealants. I'm looking to seal around marker lights, rivets, vents, etc. I'm looking to seal it up for winter. I am going to strip the clear coat off in the spring, so I took lights off and stripped under lights but will need to seal screws and wire holes. I'd like to use a sealant that I'll be able to use for other exterior seals. Vulcum? RTV? etc? What's the best seal on aluminum? This is my first Airstream. BTW its a 69 Sovereign.

Great info from incredible people that have patience for a newb like me. You all will be a part of the restoration of a 69 sovereign. Thanks again and I'm sure more questions to come.

weatherproofing questions

Got rain for the first time after removing all my interior skins. Water coming in from various places mainly around the windows. Spent considerable time and effort yesterday cleaning the seams between the rain guards above the windows and re-caulking with Vulkem 116. Heard more rain last night at 4am and went to check. Some improvement but still lots of water. Here's my questions:

1. I see Vulkem 116 is only listed for "wheel wells and underbelly". Should I not have used it to seal the tops of the rain guards?

2. Last night I could see water seeping in through the seams of the exterior. From the outside I can see the seams were caulked with something at one point but it's just a thin crusty remnant now. What should I use to go over the exterior seams? The stuff listed for roofs? Or the stuff listed for small seams/aluminum panels? (Acryl-R). Should I do anything on the inside?

3. The plastic window gaskets are all shrunk on my windows. Sounds like new gasket material is available but I've read it's a hassle to work with and it doesn't seem like it would be very water proof. Are there other approaches to sealing up these windows? Preferable with stuff I can score at Home Depot?

Thanks in advance,
--Jason

I'm far from expert on this, but I think that many use Parbond around windows etc. A little easier to use, easier to apply a smallish bead, and Parbond is colour matched to aluminum.

Acryl-R is good for between seams because you can put on an exceptionally thin bead with the applicator. Parbond will work on seams as well, if you work it into the seam with a solvent soaked rag. Captain Tolley's may work too, but I've never used this.
