That 295 is really, really good stuff. It's really easy to use the same type of rivets that were used in the orig. construction. All you need is an air compressor, an air chisel and a concave tip that matches the head of the rivet. A piece of steel, 3/4"x2"x6" will be held against the stem end of the rivet. It takes about 2 seconds to install one once the hole is drilled. The stem swells and fills any gaps in the hole, making it water tight without sealant.
I'll get a parts list and post it.
