With the way Coca Cola tastes and how it dissolves rust in some cases, it's probably a mixture of both.
Hahahaha...What's wrong with Coca Cola ? There are a lot of brands wich make cola, but with that I mean the very cheap brands...There are brands here in the Netherlands (like River, Raak, Freeway and 3ES) where you can buy 2 liters of cola wich will cost you only €0,85...I get sick everytime I drink those because they taste like s***.
Maybe you can create a tanker-car with one of those brands
Personally I really like Coca Cola, but I dislike Pepsi...
Anyway nice work on those tankers Tattoo
, I will surely use them in my games in the future
