What is the best steel for fixing rusty bodywork? and where do you get it ?
Just got myself a 200A inverter mig welder and you might say it's about to get a good work out on an old rust bucket.
cheers,
Adam

I'm using .9mm zynchaloy i think it is called. It doesn't rust as it has a coating on it, but you need to grind/wirewheel the coating off before weldiing or painting.

I have got my sheets for rust repair from scaps from the sheet metal supplier my father uses for his buisness. Probably try there for cheap material.

was about to ask that...
why would you use a zinc coating if it has to be welded and will most likely be painted?

roof and door skin good for flats but as above tar stuff is a bugga
sales rep for CIG told me best to use material from a similar age and make car as the alloy composition would be the same and you get a better weld and reduce dissimilar metal reaction

I tend to reuse whatever I have lying around, working through the remains of an HR wagon roof at present.

was going to use a few "un used panels" from work.. might be better off using older stuff by the sound of it

Apart from the Rare Spares sections, my car is all Torana... I used bits of the wrecked guard and bonnet I took off the car originally

Go to your local metal supplier and buy a sheet of 1mm cold rolled mild steel.
Otherwise known as bright mild steel.
Its easy to form and beautiful to weld.
Yes,its oily when you get it,to prevent rusting,and your hands will get dirty handling it,but its by far the best option.
If you want to store it for a long time,prepsol it and give it a coat of GMH black.You can wipe it off with thinners when you want to use it.
Or just store it somewhere dry.Any light surface rust that might appear can be quickly vibrated off and you will be giving any
newly repaired areas a wipe with rust convertor before paint anyway.

Bugger cutting up old panels,its such a pain in the arse removing old paint and tar.

thanks 4 the advise..
My next question was going to be.. what is the best stuff to spray on newly repaired welded panels? I plan on spraying the whole car ( not a show car by anymeans.. think bush pig fj40 ) I plan on only cutting the rusy bits out.. fixing that and spraying over the top of any un damaged areas...
Bad idea??? I really don't know much about paint and panel.. when the Torana was done I was a just a lacky doing what I was told so didn't learn too much about products and processes...(brother in law was the prof spray painter and did all the skilled stuff, he now lives in Austria)
