Bentley refers to D-3 sealant. Does anyone know another name for D-3 sealant refered to in Bentley, or what an acceptable equivalent would be? D-3 is specified for use in CV joint boot replacement. To apply where the metal boot cap contacts the inner CV joint, on 5K/100/200 and 4kQ models. The old stuff looks like black Permatex sealant. Dave Conner
