Putty In Wire Runs

[Capt Chad]

While we're replacing our headliner we're going to install LED lights. Now that the old one is out I see that there is an open wire run on the stbd side passing through the fir strips. On the port sid ethe run is in use. I noticed they used a type of putty to hold the wired in place inside those holes passing through the fir strips. It seems like the best way to secure the wires I'm running on the opposite side.

Does anyone have any idea what the stuff is called? It's done a great job since 1978 so why not use it on the other side.

Not sure about the ceiling but I’ve found 5200 holding hoses in place. Can you tell us if it’s hard but flexible?

Not sure what they used but sounds something like Permagum that HVAC industry uses

Since they used it everywhere else I'd guess polysulfide caulk a.k.a. Thiokol. Still available from Boatlife.

I just got back from visiting a fellow Hatteras owner who is replacing his headliner material. I checked what was used to hold the wiring in tact and it was 5200.

5200 is great stuff if you never plan to have to take it out or remove anything it's securing. Over the years, as I've had to remove things I thought were permanent, I've used it less and less. It CAN be removed, but it's not easy. It is very good for installing through-hulls, though.

Thru the years we have learned to not glue wires and hoses in place but support and seal at pass-thrus and bulk-heads.

Good ole duct seal putty works great and is not messy. Years later, still in place yet you can pull the wire or hose out.

The grey putty that Hatteras used around all of the wiring is just Duct Seal. You can buy it at Home Cheapo or any electrical supply.

Home Depot and Lowes call it plumbers putty. I used it to reseal wire runs in my FB from helm aft.

perma gum and plumbers putty are a bit different. Permagum is more elastic and sticky. Similar to bedding tape. Plumbers putty will crack if left to dry but works better in contact with water

True. Its not the same. Here is what you want:

I can’t imagine it was 5200 it takes forever to dry and you’d need something else to hold the wires while it did

I used the duct seal and it did the trick. Thanks for the info.

Here are some photos of 5200 used in these wire runs. It’s very stiff but flexible just like 5200.
