So this happened about a month ago. So I work as an industrial painter (I paint machinery) and typically when ever I get a job they tell me what paint to use and color but on this very day I got an atypical job in which they wanted me to use water based paint (latex) on a carbon steel job. Now I went to my boss and told her this won’t work because this paint will make it rust but she said “I don’t care just use the paint there going to be here next week” I got her to write down the paint I was to use with her signature and said sure.

If you don’t understand putting water on a rustable metal I generally a bad idea as rust ruining not only the paint job but possibly weaking the metal itself. I did my job after a day of prep work I painted it and let it sit for a couple of days to dry and cure and a week after that she came up to me expressing how it looks horrible as the rust was showing through the metal. I said I followed your instructions to the letter and told her again that water and air will make metal rust.

After a little back and forth she concided that she was in the wrong but asked how do we fix it. Best option sand blast it get all the paint off and use an oil based paint (it was enamel) to. She got me the sand I needed and now she trust me when I say it’s not going to work it won’t work. So that’s my story.
