I can confirm that.

I can confirm that, too. It is very effective for making lasting, strong joints with Perspex. I discovered Tensol Cement way back in the mid-1960s when I made a case for an AMU (or ATU as such was then called). I still have that item today, despite it being transported around the country in packing cases bounced around in cars, vans and lorries during various house moves from those early days until now.
