10 points for trying but I don't see it lasting long. I could not live with the reduced access and space of the hull and the fact that it is still going to hold water where you store your gear when you open the hatch, kind of defeats the purpose really (well that's how I see it anyway).
There really aren't any glue's/silicone that stick (strong enough) for a lasting seal and I think with a bit of time it will just separate from the hull all the time.
Hope I am wrong for your sake!!!
Well, thanks for the 10 points!
It's a start.
As I said, it is not tested yet, so maybe you are right.
But just for clear this up a little: there is no glue on the hull.
The bag is glued with Liquisole between two (2) original hatch sealings. Normally there is only one (1) hatch sealing between the hatch and the hull, and it is not glued either.
And of course you CAN access the storage space, but then have to open the bag also. So you are right, the access is reduced. It is an "extra" space in the bag where limited water amounts can get into without getting in storage area. Excuse me for my limited english. The 4 plastic boxes is there to show an example of how much you can store in the "extra" space.
