Re: Hatch tunnels and nylon gear delaminating.
Unfortunately, when this coating goes, there isn’t anything much to be done.
You could try flaking off what you can; and then try a nylon recoat product
used for coating nylon tents. Do a test on a small piece first.
The seams on the tunnel would also need to be sealed.
A further suggestion would be to upgrade the hatch covers to the double coated
nylon covers. The old covers have also lost waterproofing – so that way you’d
be stopping some of the seepage.
Just in case sbdy else asks this question. I seem to have found a solution to this problem.
Using a liquid naphta product for waterproofing awnings (from a camping supply) and soaking the nylon fabric from the uncoated side, I was able to makes this pretty waterproof. Seems like this is not hurting the othe hull fabrics either.
