Hi Rut, I have used Gorilla glue super gel repairing clear styrene plastics. I don't know what the material is your dealing with, but it won't work on polyethylene or polycarbonate. In my case I also used several small brass pins to locate the pieces together. Biggest issue I had was the excess squeeze out of the glue. Very tough to wipe it clean without leaving residue. I had to be inventive about clamping
as the part I fixed was oddly shaped. Finally used rubber bands.
