BanthaBob, welcome to the thread or welcome back. I assume you mean the black softer panels that go behind the leg shield and under the seat of your scooter. Usually those are made with a plastic called Polyethylene that is very hard to get paint to adhere to. If you want to use a rattle can then you can try Krylon Fusion or Rustoleum Paint for Plastic. I painted a Aero 80 that I restored with that and it worked well. On the black parts I used a rough black textured finish from Rustoleum and it looked close to the original. The only other type of paint that will stick to that plastic is 2 part automotive Urethane paint. That's the type you mix a catalyst in with the paint and spray it with a gun. You also have to use a respirator since that paint's fumes are deadly. If you are looking for a shiny finish or want to change the color of the panel, that type of paint would probably work best.
