Here are the photos of my first test on home depot insulation/craft board. You can see on the lower part the krylon fusion melted the foam, but on the upper part where is used a poly primer it did not melt the foam. When I tested to see the durability when masking with normal masking tape it pulled off a few flecks. when using note pads for masking they did a much better job at not pulling off any flecks and I found had a better seal (the paint never bled through or under) than the masking tape. I still have another test on epo foam to do.
