Mylar is best. Depending on situation, flat white paint.
If you can't use mylar, then panda will be just as problematic.
Being a retired graff artist, I could recommend some cans, but I won't. For cost purposes, get a quality roll-on flat white for a large room, or a flat-white can of rustoleum for a small space. Rusto flat is spectacular paint in any situation, and their newer caps (nozzles) work and spread wonderfully even for those who have never sprayed paint in their life.
