What should I know before welding flux core for automotive work? (self.welding)

Been doing stick welding for a bit, but when it comes to thin steel such as on cars, sticks blow right through. I was thinking about getting a flux core machine to do some exhaust work on my car because I don't want to mess with gas.

What should I know about flux core? What are the biggest cons about it?

Ah sorry, I guess it's called FCAW and not MIG. I am not using any gas to protect the weld. From what I've seen on the internet it will spatter no matter what, but I will check the polarity of the cables

Yeah that's something you'll just have to deal with. It's better if you have a dc welder and not a super cheap ac machine
