The grey lines are mine - the Trempro 635 sealing leaks. If you click on the images above, you can see them better. The black lines are seam-sealer from the Airstream factory in 1963, most of it still seals well, but not all of it. In order to find the leaks, my daughter sprayed the Airstream down from the outside while I marked the inside with a marker. I may have gone a little overboard with the caulk, but it is cheap and I only get one shot at this. Once the walls are back on it will be another 50 years before this happens again.
I'm not an Airstream Jedi, yet. Airstream Jedi would have sounded presumptuous, like I know what I'm doing. That couldn't be further from the truth. Padawan is a title I can hope to live up to.
