Can I just soak my handle material in the Nelsonite?
Yes, and many people have good success doing just this. You’ll have to test out your material to see if the penetration is good enough, but I know plenty of people who just give it a long soak. If you want to ensure there is full penetration every time, vacuum stabilization is the way to go, but if you’re careful to test, you can just soak for some handle materials.
