Does anyone have experience with field repairs of galvanized steel due to welding, abrading, etc.? Can you add any specifications if any?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Galvanizing Repair
"ASTM A 780 authorizes three accepted touch-up and repair methods:
Applying zinc-rich paint,
Coating with zinc solder, and
Spraying with molten zinc (metalizing).
The touch-up and repair method chosen should consider the specific use of the galvanized steel and the performance characteristics of each of the three methods. Corrosion protection should always be the primary consideration, but certain uses and conditions may warrant selection on the basis of other performance characteristics."

Cold galvanizing is a misnomer since it is just highly zinc loaded paint.

(Kinda like that bottle of "100% pure aloe vera" gel I have in which aloe vera is about the 3rd ingredient--but by gum it was 100% pure before they mixed it in with all the other stuff.)
