weld-40 annealed?

I'm planning on reinforcing some joints on one of my acrylic tanks. the joints are showing spreading and growing bubbles as well as crazing- spider web like cracks forming. Both in the seams. I'm planning to put some triangular shaped wedges along the interior joints of the tank. I've read all kinds of good things about weld 40 and 42. I have read however that it has to be heat treated-annealed? There's no way I can fit this in an oven.

Is this a process that has to be followed to bond two pieces of acrylic with this product? Can I use another weld-on product that will bond acrylic with enough strength to help reinforce a joint?

My friends say not to worry about this but weekly I see more and more bubbles and crazing in the seams. I'm out of town at my other residence on work now but it's really unsettling to be worrying about this 1000 miles away all of the time. I have house sitters and family that feed the fish and do maintenance while I'm away (regular work travel). But I don't think they could handle a massive aquarium bursting in my absence and save all of the fish. A situation I would like to avoid.

It's an 8x3x2.5 Acrylic which I just shimmed the stand on and leveled. I had hoped that was the cause of the seams crazing and bubbling but it has considered to progress at the same rate since leveling.

I took some pictures over the weekend while I was up there. I'll post them when I'm home this evening.

any suggestions? all advice welcome.

thanks MFK

Thank you very much for the reply. This is a silly question I'm sure but what is the tip and pour method? I think I visualize what you are describing.

I don't mind crazing in the acrylic panels. It's just the crazing in the seams that makes me nervous. Is that I sign of diminishing joint integrity?

Didysis would you tip for side seams? Or just do the bead and let it fall straight down?

Testing if I understand correctly. With the tank standing as usual, would be the position to do the bottom seams?

Also do you think putting triangular shaped wedges into the seams along the entire interior will offer more support than just weldon 40 alone?

thanks for the input. I'm hoping Wednesday will chime in soon too

I think I understand the corner itself is down with V shape aiming up. That way it fills the valley. Quite the project with a monster tank
