It really does the same thing. It softens the acrylic so that the piece can bond as it hardens.

No it isn't. Most model parts are made of PVC and the closest thing that model glue would be compared to is PVC Glue. Weldon doesn't create the bond by softening and letting it melt together, it causes a chemical reaction that makes the two pieces one solid piece.

Not sure but at least you can find model glue. I may try to bond a couple pieces of scrap together for a test.

Can you post the results? If it doesn't work, I have some WO4 and WO16 that I would be glad to send you some of it. Not sure what kind of trouble I would have with the post office trying to send it but would be willing to try for you.

I wonder if the plastic in models has changed over the years, they used to be PolyStyrene, not PVC

Oh and last I used it, they were adding Mustard oil or something nasty to discourage huffing, I would stick with stuff that has a proven history in reef applications, JMHO

They probably still are. I have never really looked into it. I just remember being a kid and running out of model glue and robbing PVC glue from my step dad.

Big difference in model and a fish tank.Models aren't alive and no water pressure on it.

Experiment done. I put two pieces together and held it for about 5 minute. Let sit for about 30 minutes. I easily pulled the two pieces apart. The glue was still like water. I then put the two pieces back together and lightly clamped them. Came back 30 minutes later. There was a difference this time. The pieces had bonded but apparently there is a reaction that occurs while they were under pressure and the pieces actually cracked.

Have you tried super glue? I made a water box for a water cooling system in my computer it bonds tightly. All edges must be completely smooth for it to bond with no leaks. But can you use it in a marine enviroment?
