a spray paint made from blended cortosis.
As much as I am a fan of the sci-fi babble and Star Wars/ME jargon... I have to point this out.
The above quote is impossible, even with the established tech in Star Wars. Read up on Cortosis. The shit is IMPOSSIBLY hard to even mine, ridiculously expensive to refine, and so rare as to be more expensive than gold is to us. Star Wars: KotOR stated that cortosis was laced into all the vibroblades the character bought because "Well... what if the character fights a lightsaber guy?" because without that, you'd have been so fucked that your ass would bleed for a week.
Example of the bullshit surrounding cortosis... read the Darth Bane novels. Darth Bane started as a cortosis miner on the planet "Apatros". He hated it, people died often, it was backbreaking work that paid for shite and ruined every piece of equipment used to mine it.
And you want to make that shit into a spray?
