^ Sorry doggie, agree was more meaning not the fusion boxes, the plug whether they are the old black ones, current grey ones or the really hard blue ones they made a few years back are very similar (though the black ones are definitely softer). That said the blue ones for a few years ago are PITA to sand.
And always got cracks near the screw those poly ones (blue) hated them as well.
The new FCS plugs are excellent I havnt managed to break them at all
