Magnetic Material Test

I went over to my parents house this weekend and had my mom test out some of her markers on a test piece of my magnetic material. I’m stuck it on top of my car and I’ll leave it up there for a few weeks and see if any particular type of marker fades faster or comes off with the rain. It’s already looking like the obvious choice of the fat Magnum44 marker is going to be the best.

Here’s the mag strip on my old car.
