Window interior leak?

Hi,

During heavy rain 3 of our '59 Tradewind windows leak. Water seems to pool up between the window frame and the cutout in the trailer. See pics.

What is the best way to repair this? I've already used aluminum gutter seal on the upper edge of the drip cap, rivets on drip cap, and the 4 seams that outline the window. Installed new bulb seals as well.

I was debating removing the drip cap to see what lies beneath.

Thoughts?

The bulb seal was great, some 50 years ago. It's basic problem is that it offers very little resistance to water.

There are far superior gaskets today that take care of the leak issue, for many many years.

The hollow "D" gasket does the job.

Here's a pic of my rear window and the seal between the window and the body. Best I can tell it is a smooshed bulb seal. I replaced all of them with this seal from VTS Hehr Window Bulb Seal

Is see the VTS also sells the "D" seal you mentioed: Narrow D Seal

I'm not sure how this seal would work with my windows? Thoughts?

How will the "D" gasket fit into the channel in this pic?

The "D" gasket does not go into that channel.

It is attached with super weatherstrip adhesive over the channel, or you can also install it on the window frame (the part that is riveted to the shell).

Would it help if I removed the drip cap on both the front and rear windows and seal the top edge of the window frame with sealant?

Which type of sealant should I use to waterproof windows?

Vulkem is used for large seams and Parbond is used for small seams.

Fastnel has their version of Vulkem, I believe it's called temp pro. Most cities have a fastnel locally. I think the big rule is not to use silicone sealers on the body panels.
