Hello, long time lurker first time poster. I have kind of a weird question. A customer wants us to laser engrave a painted stainless box mod for a vaporizer ie (Customer paints it then we laser it so the stainless steel underneath shows up). The customer doesn't want the steel showing except for the image so Cermark is out. What I am wondering is is there a certain paint he should use to cover it before we laser his image into it. I know next to nothing about paint and just want to make sure I can inform him of something that will last and not chip or anything. Thank you in advance!!!
