Cold galvanizing
Cold galvanizing is a special type of paint that is often used in the fence industry to treat cuts, welds and other modifications that take place after a metal fence is galvanized or galvanized and coated.
This type of paint is zinc rich, and while it's not quite as effective as hot dip galvanizing, that does help to protect the surface of steel fences from premature rusting.
Cold galvanizing is available as both a brush on product or a spray on product, and there are even special paint pens that allow precision application of cold galvanizing to small areas of fence.
It's important to ensure that the surface you are treating with cold galvanizing is clean and dry before you apply the product, and make sure that you cover the whole area in a smooth, even coat.
