'I told you so' is a phrase I hear often myself
Good to see someone question something rather than just accept though. We see a lot who just take what they are told/given and live with it even though it's not right.
As a FYI - a awful lot of 'hot dip galv' out of the east is only zinc plating which is washed to make it look a bit like HDG. And what's more and worse is it often looks smoother and better to the untrained eye....... for a few months. But they are getting better and at the same time keeping some western manufacturers a bit more honest so it's not all bad I suppose.
