Este tío comenta que llevo a galvanizar sucio, con oxido y restos de pintura. La inmersión en zinc quema toda la suciedad y pintura, luego un baño de acido elimina restos de oxido y un baño final de zinc le da el ultimo acabado. Y todo por el precio de chorrear. Si es cierto es muy interesante...

Frame had all the usual problems - rust, grease, paint, undercoat, etc. No sandblasting was required. In fact, the main reason I went with galvanizing is that there really was no prep. I just couldn't see blasting getting to everything and the total cost of the galvanizing was about the same as what it would have taken just to have blasted.
They initially dipped frame into molten zinc bath just to burn off paint/crud then started running through the acid baths to remove rust and then to final zinc coating.
