As a MT I often find myself lacking in reinforced glass when I have little side projects running and have to fix the Rasputin's windows, especially if there are other MTs around that need some R-Glass too!
Benefits:
Considering that Reinforced Glass can't really be used as a viable defense against Aliens, I see little to no reason why the cost of the material shouldn't be lowered. It would benefit the engineering department with making the job more fun again in general. MTs would always have enough glass to fix up the Rasputin and even get some little projects of their own going, while not having to bother cargo with ordering more materials.
Details:
I'm not sure with what amount of materials everyone would be happy, but currently producing ten sheets of reinforced glass at an full autolathe uses up almost all of the metal and glass inside. I don't think one would have to make the glass super cheap to produce, but maybe you could half the price?
Implementation:
I'm no coder magician, but I think this would only require minor changes in the code.
This is what I mean with "little side projects":
