I have two spare frames (f&r) in for sandblasting at the mo... And then I'm going to 'attempt' to get a place to galvanise them. The thing that concerns me is how to get to the inside. Being a hollow section, I imagine that during manufacture they never ever coated the inside with anything. They're not phosphate dipped like the bodyshell is, only spray painted black on the outside.
Once blasted, the 'clean' steel components are pickled (whatever that is? anyone?), then oven baked then zinc dipped. That should buy me a few more years.
Excellent pics. Totally shocked at the cracks on the rear frame. Never seen that before. I had assumed that when they fail, the welds quit after severe corrosion. Wow, just wow.
