I understand that's what weld on states. But from my experience it doesn't do well at all on pvc. In fact if you google sandiegoplastics, you'll find a list of various weld on products and what they will adhere to. They mention pvc's etc in some not in others. However I have had poor luck myself trying to use it on anything else except acrylic. Many people have reported poor results with cell cast over extruded acrylics. How is your experience with it and materials of different characteristics?
Well I would say,
I have not really had super luck in gluing any plastic to speak of. I mean the PVC work has all gone without a hitch but, I used the PVC glue. On anything else, not so good. That is why I try to make every thing, and do everything out of glass. It is also why I suggested to silicone in pieces of glass to strengthen the tank. On a side note to that......if NEPTUNE were to use glass in the manner I had suggested he would be able to remove the foam wall with out having to ruin the tank. After he glues on those pieces of acrylic (witch will have to be after he installs the wall) he will not be able to get the wall out. For me that is a big problem, maybe it isn't for NEPTUNE.
Now then, I would glue PVC fittings with WO#16 in a pinch. I would bond PVC to acrylic in a non stress situation. In NEPTUNES situation, I don't think the glue is going to do any real work, as he is going to be bending the edges over the trim. The glue just has to hold the acrylic to the top, and not do any real work. So what ever it is he has might work?? I would scratch up the surfaces of the two bonding pieces, using 80 grit sand paper.
If it were my tank, I would look at siliconing in a piece of glass on the front and back pains. The glass would also help the floating issue that the foam wall is going to have. Heck I don't see why it could not be lower in the tank and covered in foam as well giving a shelf for frags to be placed upon.
