Sliding hatch fix

Since the beginning, we have observed that under heavy rain, the water gets its way into the cabin though the sliding hatch. The problem was later identified as a manufacturing flaw, because the beneath of the hatch is not flat and drops coming from the edges of the hatch flows back to the cabin.
The other issue is the weak corners and after a few months of light use, the front corners cracked against the ends of the sliding track.

The problem is the small thick of the laminate on the lips with the soft Airex coring behind. So I've decided to remove small piece of the coring and fill it with thickened resin.

Here you can see the cracks on the corners (gelcoat already sanded)

With masked underneath I've filled the gap with thickened resin.

Final stage painted with gelcoat and buffed.

To fix the water intrusion, I've installed 4mm height self-adhesive brush pile seal on the track of the sliding hatch. The other benefit is that I can now slide the hatch very easily.

The second brush seal track was also added at the edges of the sliding hatch, which helps the water to drop off the on the edge of the hatch.

Seal is working just fine.
