Weldon in Calgary Today

If your really stuck you can mix acrylic scraps with acetone, it'll dissolve it and you can make whatever consitency you want use it just like weldon. I've used that mix to make entire tanks and fuges. Another thing I've used is that really thin plastic model cement, the stuff with the brush in the bottle. I've never used the model cement for anything that holds pressure but it does hold acrylic with no pressure.
