Okay Air Forum Folks,
I am preparing to attach new vent caps for the Refrigerator and Heater Flues and the roof jacks for the kitchen and bathroom.
From my research, Sikaflex 715 is the best sealant out there, so I've got that part covered, but now I'm wondering about the best way to fasten the new plastic parts to the roof: In pulling them off, the old refrigerator flue cover was attached with rivets, while the Heater vent cover used screws, but there's a good chance neither was original equipment.
Anyone out there know how they were originally attached back in 1968
? And what about the plumbing roof jacks? A friend of mine recommended considering just using a high-grade varethane adhesive like they do for car windshields...
