Rub Rail...-gctid367211

[Guest]

Might Have posted this in the wrong place the first time...

It looks looks like there is a silicon sealant (some of it coming off) along the bottom edge of the rub rail where is contacts the hull on my '08 192 Cuddy . I am thinking it is time to remove the rest and apply new. A couple questions - What product would be the best for this? I have seen 5200 suggested, but I am not sure about that. Also, should I do this along the top and bottom, or just the bottom. I am not sure if the top is a potential point for water intrusion or not. Any other suggestions welcome.

Try 3M's product guide; it says that 5200 is only rated as "good" for rubrails, and 4000UV is rated as "very good". They list both as removable, and 5200FS is permanent.

I would use Bostik Marine 920, and 920 Fast Set if you're pressed to relaunch right away.

I am not a super experienced boater here, but have a 2555 ciera that we purchased last year, and I can tell you that during rehaul of the upholstery, we have a decorative inner trim rail that runs the full perimeter of the boat, and it has been completely ruined because the sealant has come off in places during its years. It was sealed both top and bottom and at least on ours, you can see where it might leak from above so ........................I would do both.

When originally installed the factory used clear silicone seal. Dow Corning products were used. The bottom of the gunnel was sealed and the pinning holes and fastener heads under the gunnel rubber were sealed. A small, carefully applied bead on the top can also be installed to prevent water from leaking down under the gunnel and passing into the cabin via the fasteners used to install the gunnel. One word of caution, seal on top of the gunnel collects dirt and can yellow or change color making it obvious so use good quality seal and on the top keep the bead small.
