Show/Commode seat too sticky

So I just got a Shadow 9000 from ActiveAid to replace my E&J. Part of how I positioned myself on the E&J was to lean back causing me to spasm which would slide my butt into a good position. The seat on the Shadow is too sticky and my butt won't slide. Was thinking maybe if I put something on it, like water or GB powder, I might slide better. Thoughts?
