The Soft Body that I use has an Anglers Choice label on it. It comes in a Thick and Thin version. It is water based and thins with water. I only use the thick version and put some in a different container and thin out if I need a really thin application. I apply it with a paint brush. It cleans up with water. You can also dip the heads of flies into it. This works better with the thin formulation.

I use it for coating crease flies in place of epoxy. I also use for coating the heads of flies or for anything that I want to have a flexible coating. I also use it to apply to synthetic materials when i want a soft but full head on flies like the mushmouth. In many cases it can be used in place of Softex.

For really thick applications I find it works better with multiple layers rather than just one really thick application.
