Go to wheel, gamble on the 67% side instead of the 33% side. Every wipe I make 8-10k scrap on the first day sitting in outpost, buy my metal frags and auto turrets, and I’m set.
Method number 4: Become a professional gambler/risk manager and get rich with the roulette from bandit camp 😎... Aside from that, its just better to farm tunnels and monuments, in a few runs (about 15mins) you can get easily 1k scrap + other useful items
You forgot another great method to gather scrap witch is Farming the Junk Yard, Not just because of the barrels and boxes, also because you can find Diesel and use the Car Crusher witch I believe it can give you 500 scrap every time you go.
fyi horse poop farms are completely pointless on any high pop server as a single other player selling fertilizer makes the time wait and the fact you have to being competing instead of afking a waste time
Scrap tea info is incorrect, Basic scrap gives you a 100% boost for 30 minutes giving you 4 scrap per barrel every barrel, advanced scrap tea gives 225% boost for 45 minutes which gives you 6-7 scrap per barrel, not by chance either, it gives 6 scrap, next barrel 7 scrap, then 6 again, then 7, and on and so forth, pure scrap tea gives 350% boost for 1hr which gives you 9 scrap per barrel every barrel
