Sunrader berth window cracked in the corner

[sweetleon]

I was doing a little cleaning on the exterior of my Sunrader and discovered that there's a crack at the top corner of one of the wraparound berth windows. I know those are notoriously troublesome, so I'm hoping to find a way to get this remediated before it gets any worse. And, as usual, I'm hoping somebody here has ideas.

As you can see in the photo, it cracked and "escaped" the gasket a bit.

Would it be safe to use a bottle jack (with a wood board at either end to distribute the pressure) to pry it open a bit and get the window back inside the gasket? If I could do that, I'd put some sort of epoxy on the crack to keep it from spreading.

Thanks,
Lenny

The best way to stop a crack spreading/propagating is to drill a small hole at the end of the crack.
