Hi all, firstly I would like to say what a great forum - I have just spent a while reading through heaps of articles that have given me some great ideas for my rebuild - plus also an insight into what a bunch of "mini mad nutcases" you all are

.
The question I have is what types of metals are referred to as non-ferrous metals - are car bodies non-ferrous metal ?
Why I ask is I have a can of primer that advises it is excellant adhesion on bare metal but do not paint on non-ferrous metals without using etch primer first.
prior to painting I have always used etch primer - this is more a question of curiosity rather than anything else.
