SILICON AND GLASS BEADS DON’T MIX
Many times you will have an aluminum head with some left over silicon gasket on the surface. Attempting to bead blast the silicon off will only result in a damaged cylinder head. The aluminum will continue to be worn away by the abrasive glass bead while it bounces off the silicon. When you finally remove the silicon you will be left with a worn aluminum surface that seems raised where the silicon once was. Clean all silicon off the before attempting to glass bead any aluminum part.
