I'd stay away from what we call Zintec in the part of the world Ryan. Ordinary old cold rolled is going to give you enough trouble as it is - unless you are Peter Tommasini etc... Just use a weld through primer on the laps and boxes when you are putting it together (standard collision damage stuff these days) and get hold of a decent spot welder if you can. I was given mine as it won't tackle the latest stuff, but is fine for what you and I are doing.

Thanks Richard.
i was looking at this, mainly because it had a material specification listed against it. need to do a bit more research and ringing around yet. The material spec will no doubt be important when it comes time to register a scratch built chassis. Always nice to know what your dealing with. https://handysteel.com.au/sheet-metal-bright-sheet As for the spot welder i picked up an older Tecna spot welder. very similar to this. does not have the timer controls on it. just the one button, that keeps it going while you hold it down. The electrodes tips need a bit of a clean up. I will try and give them a clean up with the lathe. https://www.machineryhouse.com.au/W092

According to AWS Welding Metallurgy Vol 1, "The purpose of manganese is generally threefold: (1) combine with oxygen in the molten steel and thus assist in its deoxidation, (2) tie up any sulfur that may be present to avoid the formation of iron-sulfide inclusions that cause hot cracking, and (3) promote greater strength by increasing hardenability of the steel. A bonus-effect of these actions by manganese is that the fracture toughness is usually improved."
