Aistream Repair Shop?
Something to consider before having the coach re-sealed. What surface preparation is being planned prior to the repaint? If the paint is to be stripped with a chemical stripper, the re-seal should wait until after the paint job as the stripper will likely remove the sealant materials.
The Airstream plant in Jackson Center, Ohio is always a possibility. Sometimes, there may be a Vintage Friendly Airstream dealer nearer your location who could be helpful with repairs. I have hear good things about Out of Doors Mart in Colfax, NC -- but I haven't had any personal experience with their service center.
Another option, and this is one that I have been using since moving to Southern Illinois, is to take some time to learn about long-time RV dealers in your area (not necessarily Airstream dealers). In asking around the RV community in my area, I found the names of two long-time dealers (both more than 30 years) -- then, I visited each and spoke with the service managers about their comfort level working with Airstream products -- one of these shops was quite comfortable working with Airstreams and has since done quite a bit of repair work on both of my coaches -- most recently, a new blackwater tank on my Overlander.
Good luck with your investigation!
