years ago often the metal wasnt treated at all.

For example one of the reasons early 911s are worht more is that they rust as a pastime so are much rarer in rust free condition . They only stopped rusting when they decided to use galvenised panels

I've been using owatrol oil in my paint for some time now. But it's only recently I've read the back and it turns out it's a rust inhibitor. Sooout of curiosity I tried some on a rusty scrapper I did 2 test area's 1 where I rubbed down the rust and the other where I didn't. Got to say I'm quite impressed it penatrated through the area I didn't rub down and has stopped any rust returning. It's cheaper than an equivalent hammerite and you get moreffor your money. Win win in my book

The Elan's body is pretty clear of rust, which is very good for a 47 year old car!

Vauxhalls and Alfa Romeos built in the 60s and 70s started to rust before they left the factory.
