Gray water holding tank repair

[Flyview]

Hi guys,

My gray water tank is leaking at the junction between the tank and the neck that leads to the outlet. What kind of plastic is it made of? I'm thinking of sanding off the corrosion and then coating the crack with some sort of plastic glue or JB weld.

What do you guys suggest?

Here's a picture:

Is this highlighted area the crack. If so grind a V into it with a Dremel tool or burying bit so you have a rough surface to adhere too. then add a good layer of JB weld or any good two-part epoxy. cleanliness and a very rough dry surface are key.

I have also had good luck with Flex Seal rubber spray paint, take a few coats.

Yup, I think that's it. Are you saying to make the cut deeper?

Thanks! How did you do it?

EDIT: Opened the link and there's literal video instructions, awesome. So I'm guessing it's ABS plastic then? Where was yours cracked? You think I can just apply some of that resin along the crack or do I need to add extra plastic and stick it on top like they fix that hole?
