Hopefully someone here can point me in the right direction. Maybe the saltwater folks?

I'm looking for a translucent plastic material similar to scudback but with small reflective flecks in it and/or a reflective/prismatic sheen (in clear). I'm looking for this material in clear, light blue, chartreuse, and orange. It needs to be at least 1cm wide, but could come in sheets that I could cut in strips.

If someone knows what I am talking about, then they will likely know what I want to use it for. And I need copious amounts (for personal use, not commercial) of the stuff. If anyone can plug me in to a good source for the material, I will share the secret with them...if they don't already know.

Thanks.
