A hatch was very leaky and had to be sealed quickly. Was my first time, but I think I not bad to get it. At the same time, I have returned the hatch (front opening).
After the Demmontage was right, why it was leaking, but sees itself.
So it appeared. I hope it holds the next 15 years.
Unfortunately I have to do in most hatches. But if you did it once, it is twice as fast at the 2. Luke
