I guess I won't be doing that then! Funny, the A cat guys glue them in, but nobody else does. I've already had to change out hulls for crash damage, so I guess it's just as well they were not glued together. Here's the funny part, the -new- hull leaks 3x more than the old hull! I don't know from where, I'm going to to soap it up and blow air into it to see if I can find it.
