Centerline leaking!

a wirw wheel on a drill will clean it up. Before resealing it bolt it on a axle or drum . Or just get five bolts some washers and nuts. But make sure you have the halves pulled together. also clean the wheel where you are sealing it with some sort of solvent or thinner. Put a liberal amount of sealer on it and use a large round washer or something simular and go around the wheel to smooth it as even as posible to distribute the wieght evenly.Let it sit a day or two before loosening the bolts. I have done many sprint car wheels to save inner or outer halves. Just some tips you might use Steve
