About MotorGuard Run Razor Blocker Set
These cleverly-designed tools will take care of any problem areas that crop up towards the end of the painting process. Run Razor holds standard razor blades at a precise angle to shave down semi-hardened runs, sags or dust between color or clearcoats. Just pass it gently over the surface, dialing down the blade position indicator in.001" increments until the imperfection is gone. Run Blocker provdes three different contoured aluminum blocks that can be used with wet/dry sandpaper to finish runs that have been cut down with nib files. Can also be used for block sanding body filler or primer.
