I don't own an airbrush, and I know that at least with the Spazstix chrome you need to back it with a water-based backing. Spazstix doesn't offer one in an aerosol(rattlecan) can. Does anyone know of a rattlecan alternative or if there is a water-based backing even available in a rattlecan? I have a big Tower Hobbies order I'm putting in tomorrow so hopefully any suggestions are available there.
