Review on 🔧 Permatex 80036 Valve Grinding Compound: Precision in 1.5 oz. Gray Package by Lawrence Crespo

I bought this connector to add extra rigidity to the screws when the screwdriver or bits start to slide over the screws. I find this especially helpful when trying to remove Phillips head screws which can have the head loosen making removal much more difficult. A light touch with the tip of the screwdriver is enough while I press on the screw and turn the screwdriver. An excellent product to always have at hand, even if I've never sharpened a single valve!
