To note, follow this guide at your own peril. I fully expect parts, if not all, of this strategy to be patched out in the near future. Additionally, 'infinite stuff' sounds great on paper, but reduces enjoyment of the overall game.

First and foremost, to be able to follow this guide you need to be familiar with some mechanics in the game.

First, there's a relationship status with each faction, and there are two you must have trading relations with for this guide to function. The Daydream Chemists, and SBN.

Next, all weapons/ammo in the game can be disassembled into the base components required to craft them. Of particular note to this guide are Batteries and Chemtrail. Both of these, when disassembled, result in Glass and Acid.

Batteries and Chemtrail

Now, part of this guide boils down to luck, however it's the sort of luck where you're at the casino and you're good friends with the dealer, and they're cheating because they know there aren't any cameras at the table and they're really good at dealing from the bottom of the deck.

Step 1:
As mentioned before, find yourself some Chemtrail or Battery ammunition. The more, the better. Ideally start with at least a few stacks of both.

Step 2:
Fly to Deimos, and dock with Warden-D. I want you to pay close attention to the items they barter, and the items that they give out (even at max rep).
 
 
Simply dissassemble all your Chemtrail and Battery ammo (but no more than a stack at a time), then exchange it. Occasionally you will get a weapon with Chemtrail in it, a full stack of Chemtrail itself, or any of the other possible rewards which include item recipes and antidotes.

Step 3:
At some point, you will run out of Chemtrail and Battery ammunition. Most likely. Maybe. If, at any point, you ever do, you now fly to the Moon, and this where where SBN comes in.

Give Moon TC your antidotes, one stack at a time. You will be gifted with lots of laser weaponry (which have batteries as ammo, and can be disassembled into several useful components), and of course, entire stacks of batteries with which to return to Step 1 with.

Step 4:
Profit.
