One, it's not the best galvanise job in the world and two, as soon as any hole(s)get drilled through it- as they do-to accept the various nuts, bolts, frames etc., the whole concept of it being galvanised is undermined.
Just to re-assure you a bit, no the idea of galvanising isnt undermined. Galv isnt like paint intended to protect just by covering the surface. It also protects by electrolytic action when penetrated. Sure this means it will gradually erode away but if the chassis is hot dip ( which is what it looked like when I had a quick glance) then this will take a long time. That said, probably still better to waxoil it.
I don't disagree at all with what you say but two thoughts still strike me: (1) given the proensity of the chassis to flex, surely this must crack the coating and undermine it to an extent (2) in similar vein, as soon as any hole etc is drilled throgh a galv surface, doen't this, again, detract from the protection?
I may be wrong here and I'm no metallurgist but I thought this was why all the best resto jobs went for powder coating?
As I said, happy to be corrected
