I was building a FT Simple Storch for someone and since it was for a new pilot as a trainer it needed to be easy mainyain oreantation with. The wing bottom was painted with neon orange Krylon and it was great. The back half of the plane was painted with Krylon metallic silver. I lightly sprayed it and walked away for 5 minutes not expecting anything to go wrong. When I came back I saw the whole tail was drooping and wrinkled. Upon further inspection I found everything that had been painted silver had a lot of foam dissolved. It probably has to do with what is inside the paint, but I would stay away from the Krylin metallic paints.
