Hi guys. I'm pretty new here so I find myself asking a lot of questions about things that have crossed my mind from time to time.

Painted metal. Examples: my coffee table has metal of some kind wrapped around each leg, and then welded to cross members. My patio set has shaped and welded metal on the chairs and table frames. These are all black.

How is this stuff painted with such a durable finish? I would like to make (after I learn to weld - lol) a table with rectangular metal legs. I know for a fact if I hit that framing with Krylon it would scrape off with a fingernail, even with a sanded scuff finish on the metal and a primer coat.

Inquiring minds want to know.

Thanks.
