Since bringing home my new 1960
Safari, we've had a lot of rain here in the east and I've discovered two leaks. One seemed to be coming from the square 14" Hehr aluminum vent, even when it was closed. I assumed it was the seals around it and per a couple of other leaky forums I bought some Vulkem and Parbond and was prepared to have a go at the seams around the vent. This morning, after no rain for days, I got up on the ladder to inspect the seams and they look pretty solid. I then went inside and opened the vent and a steady stream of water poured out for almost 30 seconds! It seems water is getting inside the skin of the vent itself then leaking out around where the crank arm holder meets the vent cover. I also noticed that the triangular plate that holds this vent cover on is unattached and wiggles around when you turn the crank. (It doesn't go all the way around because it hits the lip.)
So based on this information I've concluded that a) the Hehr aluminum vent cover has two layers of aluminum and a pocket of air (perhaps providing some insulation) although my original assumption was that it's just a single thickness of aluminum.
The rivets holding my vent on have sheared and this is allowing water to get into that aluminum pillow cavity and the water is then finding it's way into the trailer.
Can I simply rerivet the aluminum holders onto the vent?
And when one does this what should one seal the rivet with. Parbond? Vulkem? Or something else.
What size rivets should I use and can I use Olympics or should these be bucked rivets since I have access to both sides?
