Re-bedding Forward Hatch

[denpooch]

Hey Folks,
I would like to re-bed the forward stateroom hatch. My fiberglass guy ran a moisture meter on the deck and determined that I am likely getting water intrusion via the hatch.
Can you please give me any advise and insight on the removal and rebedding process?
Below deck, above the berth, there is a screen/shade retractable (forward-aft) devise. Should this be removed before proceeding? How is that accomplished as it looks like a finished product.
Per Carver, I am going to use 3M 4000 UV sealant. (I just finished rebedding the deck hardware).
All thoughts are very much appreciated.
Thanks

Use butyl tape instead of caulking, it's a much better product for that type of thing. It's leaking because caulking was used in the first place. Here's a link to a thread where I posted some of the benefits of butyl tape over caulking in another thread:

On my older Carver, the light was leaking. During our restoration, I completely took it apart. Come to find out there are two layers of fiberglass - the deck and the outside layer, with nothing on between them. about a 1/4 gap at the front and over an inch toward the aft end. So the tighter the screws were made, the more deformed the thinner top glass became. So It spent some time and hand formed some treated wood that became a filler. all the way around. Thus, when tightening the screws, everything was in tension, thus had a great chance of sealing.'Which it did!.
