<VV> Yes, WELD GALVI---

[Frank DuVal]

BTW, all this talk about not welding galvanized steel, and now the 
mention of zinc rich paint, brings to mind the weld through primers we 
use in the auto-body collision field. We are supposed to use this weld 
through primer to restore the corrosion protection that was there from 
the factory on  newer cars. What is the main component of these primers? 
Zinc! They are zinc paint, kind of a cold galvanizing process in a can. 
So body shops doing it "right" are spraying zinc paint on bare steel and 
then welding zinc whenever replacing body or structural panels. And of 
course you can use this zinc paint to help keep corrosion out of pinch 
weld areas and other joints when welding new panels in your Corvair. It 
would not be needed in butt joints.
