How to fix a cracked vent housing

[ezriders]

I have a Fantasic Fan on my Montana that has a cracked housing. Its a hairline vertical crack that allows water to drip from the kitchen ceiling. They discontinued making this fan and I cannot find a replacement shroud. I was wondering what I could use that would seal the crack. I thought maybe epoxy or pvc glue, or maybe Dicor non sag sealer. Any suggestions would be appreciated as I cannot afford to buy a replacement fan.

Eternabond Tape... no leaks...

I had to use clear Gorilla tape when we were in Colorado and a large hail storm destroyed one of our vent covers. Worked great until we could get it fixed.

Have you contacted Dometic? Beyond that I would advice putting a bit of Dicor or Eternabond over the crack. Or you can use this opportunity to install a shroud:

I used Gorilla Tape on a shower skylight that had a big crack/leak. Also, the old reliable, J-B Weld will work if you need to leave it for an extended period of time. I'm surprised that Fantastic Fan cover would break, but have you contacted them directly? I did when one failed and a complete brand new fan landed on my doorstep the next day. Yes, I am aware that Dometic purchased them but understand that they are still good to work with.

if you are referring to the cover, you can use any one of the products mentioned above, or use fiberglass to mend it. i fiberglassed it and an a/c shroud, excellent.
