Hi guys,
So - I'm cheating here... I have a 1956 Silver Streak Rocket, not an airstream. I'm in the process of restoring her, and I had to replace the Lower left-rear panel due to corrosion. The window was damaged at one point, and the years of water leaking in corroded the exterior skin and the ribs to the point where it was just white dust...
I've ordered a new sheet of 2024-T3 aluminum, and instead of bending new C-Channels, I am using a section of 0.125"x1"x1" 6063 Aluminum channel. I'm actually replacing the ribs all around the perimeter, in an attempt to beef things up. I've already replaced the entire floor with 3/4" plywood (A-C Exterior, 2 coats of polyurethane, nice side facing down).
Question is this: Where should I apply sealant to the new skin? I'm putting a dab of Trempro 636 on each rivet, but I also want to run a bead. To me, logic says to put it up high. The panels overlap by 4", so I should put a bead on the inside of the skin where things overlap. Then if (when) water does get in, it won't just sit in between the two panels, but leak down to the floor (hopefully giving me advance notice).
Any thoughts to this, vs a bead in the middle, or one down along the line of rivets?
