I used a Stapes Item# 386943 magnetic inkjet sheet and am spraying clear enamel on top. I’ll be cutting out these guys and displaying pictures of the badges mounted on the grille over the next few days. And we’ll see whether the badges survive staying on the grille holder for my 50 mile commute. My first testing showed that the badges stayed on for a short stretch at 50 mph. The nice thing is, I have the Photoshop file saved, so if I need to get a thicker magnetic sheet, it is not a problem to make more. Once I know that these will stay on, I will move on to making something more original.
