Just started to help restore my daughter's a 20 ft 1967
AS Overlander. My first priority is to seal up the outside to fix any leaks. After some recent rains, I only notice some water in two window sills. All the gaskets around the windows are deteriorated. May not be the original gasket, but it's white, about 5/8" to 11/16" wide, & 3/16" thick; looks like 2 side by side double "D" with 2 little air pockets in the gasket. I would appreciate any advice about replacement gasket (white or black?) I saw some with adhesive backing? or should I use a special adhesive?
I am looking for any other water leak sources; loose rivets, skin separations, vents not sealed, running lights, etc. Overall it looks real good, but outside patches around vents are suspect. I see some old water damage on plywood wall at bathroom wall, just under a roof vent where two rivets are missing that attach the top cover to the crank down. There was duct tape on the outside which must have stopped the leak. I will put new rivets in there.
I will be replacing all the inside gaskets on the crank up roof vents. So I welcome any advice as to proper gasket and methods, adhesives etc.
