I use a Harbor Freight poly carbide disc on my grinder. It works FAST and strips right down to the metal but cannot get into corners or really tight areas. So it is not the final word. For me, I strip what I can with the disc because it's fast and cheap and my labor is free. The tight areas will need sandblasting. A few light passes over the already stripped metal will give it a good texture and reduces the heat that would be created by sandblasting alone. Check my signature and view recent posts on my BLOG. I recently stripped several panels.
