Roof Leaks

[Skyhawk13205]

I must have a real talent if my thread about roof leaks evolves into stripper pole technology.

got this gasket today, seems workable. I may need some rigid plates over the Aluminum cover to compress it thou, unless I employ some strippers to stand up there all day.

Did you make that cover yourself? it does not look like the OEM. The perimeter might have to be bent over to help water sealing. When I made patches on airplanes we would bend the ends slightly to give a slight spring to help clamp the edges.

It's what came on the truck. Probably a MME product.

The gasket is for weapons systems. It's never used on the sheet metal cover. The cover uses one strip of adhesive neoprene foam, and sikaflex. The gasket really is not going. To be helpful here. It's just adding two additional surfaces that need to be sealed and that's just extra points of failure. RTV is otherwise known as FiPG - Formed in Place Gasket...... Implying that no additional gasket is required.

You could also do the same thing with a bead of spray foam. Spray a bead, let it cure then place the cover which will compress the bead and form a foam seal.

I used Henkle on my personal truck and we use it on our Overlanding Campers. Tough, takes paint. You can also use Kommerling Korapop if you can get it. Ebay.

I put silkaflex on both sides of the gasket and put it back together. I put butyl tape around the groove just to fill it in. Tired of playing with it.

I made a cover for the roof rack that's one of our old 1/4" laminate real estate sign sheets. two pre-painted sheets of .008" aluminum with a solid polyethylene core. Pretty tough stuff. That should reflect some heat.

Yes, "tired of it" is the feeling I had too. Especially when you start putting nice electronics in the cab. By the way, that's a nice rack.
