Black tank seep leak

[ua40j]

I have a seep leak around the rotocast connector that comes out of my black tank and connects to the black sewer plumbing. It looks like Winnebago put the connector in after the tank was cast, then welded it in.

They put some kind of glue/sealant around the connector and the leak was under the sealant. I pulled the old stuff off and now need to replace it.

This isn't a stress crack or break or anything structural. Just a weep leak that's annoying and rusting the supports for the tanks.

Any thoughts on what to use?

JB WELD has at least 2 products that imo would work in this application. i have the STIK WELD and WATER WELD. after reading the packages, i would try the water weld first. it even works under water.
i have successfully used other jb weld products but not these ones yet.

JUst got off the phone with Winnebago. 'Al' in Service told me the tanks and fittings on the tanks are polyethylene rotocast.

JB Weld will not adhere to polyethylene....but my new best friend ETERNABOND will!

Wish me luck....we patch this week.
