Save you a lot of money and buy Tamiya Air Brush Cleaner instead of expensive Extra Thin Cement. I use the Air Brush Cleaner as glue and the behaviour on the plastic is the same.

Extra Thin Cement: 130 euros per liter in my country (5,2 euros for 40ml)

Airbrush Cleaner: 36,4 euros per liter in my country (9,1 euros for 250ml)

In conclusion you get a discount of 72 percent.
