Hope I’m posting to the right area. Have a 2017 JayFlight and need to reseal around the tops of the tail lights and hatches. Jayco said to use DICOR non sag lap sealant but that is not what was used when it came from the factory. It looks like they used butyl tape around the hatches and windows but along the tops of the tail lights,clearance lights, and hatches they ran a bead of some other type of sealant. Any suggestions would be appreciated. Thanks

I would (and do) follow the manufacturer’s recommendation…DICOR.

Only lasted 4 years, and you want to use the same stuff?

Thats right, you want the Dicor non-sag sealant or equivalent brand, its just an outdoor window/door silicone caulk labeled for RV use. Butyl tape is used for initial install. After a while its wise to run a bead of caulk to keep the item sealed. On tail lights I usually choose a clear caulk. Roof hatches and kinda flat applications use the self leveling stuff.

Dicore is polyurethane baised. Get that or another polly baised caulk. Its not silicon.

Thank you all for the quick replies.

You can also use OSI Quad it will maintain a rubbery consistency. It is composed of elastomeric polymers and high quality synthetic resins. This product offers the superior adhesion characteristics and unmatched elasticity found in high performance sealants. It yields a tough, rubbery seal which resists outdoor weather-related elements.
