K&W Coppercoat Gasket Compound

We use this product on the tops of the cylinders, where they meet the cylinder head. A small application helps prevent combustion leaks in this area. 4oz tin with dauber. Use on aircooled VW engines where you are not going to use a head gasket. We use this on our Type 4 engine builds after lapping the cylinders into the heads. This now comes in an aerosol can, not the dauber type can pictured.
