Always get good advice from Forum Members.
I have a Kenmore Humidifier. It had a removable storage tank that can be filled and put back onto the unit and it keeps the reservoir filled.
As I was filling it in the kitchen sink it fell over and the two piece tank came apart. I took it all the way apart and cleaned it good.
I need a good glue to put it back together. The glue residue that that was on the tank was kind of rubbery. It needs to be waterproof and needs to be pretty strong. The tank holds a gallon of water.
Any good stuff out there?

What? Not FlexSeal?

How about regular superglue, as long as the fit is perfect?

There is a super glue type that is specifically for plastics. I have used it with success but it maty==y depend on the type of plastic and its ability to be compatible with the glue.

Super glue would most likely work.

Some plastic can be welded together with Acetone, most cheap finger nail polish remover is made of acetone. I would try that first. Tape the plastic together and then apply acetone into the splice. You should be able to remove the tape in 10 minutes. If it holds you are done. If not use super glue.

For gluing ... http://www.thistothat.com/

I've used this stuff before Plastaid and it works pretty good. Just do any mending outdoors because it reeks to high heaven when in liquid state.

Take a look at Zap-A-Gap. I use it on fly tying.

e-6000 will do it

3M 5200
Make sure it doesn't get on anything else. Once dry it will not come off.

While not cheap, 3M DP420 is one of the best all-around epoxies for plastics that you can find. And by "best" I mean that it can typically bond the widest variety of different plastics together, often working where other regular glue options do not.

I think DP420 only comes in the cartridge that requires the mixing nozzles and applicator gun to push it out of the tube, driving the cost up further. But if you can find it in a ready-to-go dispenser that doesn't require the cost of the extra items then I would go with it over other options.

Something like the 2-part Gorilla epoxy may be a better fit for a lower budget option:

Do you know what kind of plastic it is? The glue type used is dependent on that. If it's acrylic or polycarbonate, then if you look at your local hobby shop for plastic welding fluid it should do the job nicely. I've been told methyl ethyl ketone would work nicely for this as well, but cannot confirm nor deny it because I haven't tried. There's another product I've used whose name escapes me that's thicker and fills gaps better. I'll check when I get home.

CA glue (super glue) will probably get the job done, but tends to leave a fairly brittle joint.

E6000 is some good stuff. I used to use it for all kinds of stuff.

I just glued it with super glue and clamped it together. I am going to smear some clear silicone on the outside of the joint and see.
If it doesn't hold I will try something else.
Thanks for all the replys

Since it's a tank, you'll want to use some glue that provides some tensile strength.

Superglue is quick and easy but it's also very brittle and will likely fail over time.

I'd use some sort of a two part mixture adhesive like Epoxy or JB weld.
