The problem is it has to be used in a WELL ventilated area, or preferably outside. It also comes in sprays that are non-polluting to the atmosphere, non-chlorine formulas. </div> <div> </div> <div>Those of you with old bowling alley for workbenches, it does not have a crown at center but is made dead flat.
