Anyone know of a source for small quantities of zinc ammonium chloride?
I am having to occasionally do a little milling on these French boat anchors I sell. Seems the metric shackle holes are not quite large enough for US shackle pins. The anchor shanks are galvanized steel and really need to be regalvanized in the areas I have milled. I have gotten good results using a small zinc pot and had a very small supply of zinc ammonium chloride for flux that I begged off a real galvanizing shop but the flux has run out and I am hesitant to try to mooch some more. I have found sources for 50 pound bags but I just need 4 or 5 pounds.
