I am intrigued by the glowing TT comments regarding cold galvanizing spray.
Since my experience is so much to the contrary, I must be “Ralphing
up” the process somehow. I’m hoping someone here can correct the
error of my ways.
I have tried 3 different brands. I have enthusiastically read all the promo
stuff: “Rich with self-sacrificing zinc, creating a durable bond, etc.,
etc.”
I have applied the spray paint directly over clean, existing galvanized steel.
I have applied it to new, buffed (with steel wool, and/or emery cloth) steel,
and to chemically etched, new steel. I have allowed it to “cure”
for 12 weeks. I have yet to achieve what I would consider a “bond.”
To wit: the paint can be scraped off down to original surface with the
slightest effort. In fact I can even rub it off with a callus on my thumb!
What am I missing?
Thanks,
Jim - WS6X
