Your Air Cooled VW Beetle Engine Bay could very possibly need this panel. This panel is almost always rusted bad enough that it cant be repaired. It is used for structure of the body as well as a necessary engine bay seal retainer. You have to have a good seal between the engine tin and the body in order to keep your Vintage VW Engine functioning at the correct temperature. The panel will arrive in bare metal with a little oil sprayed on it to help prevent corrosion during the shipping process. You will want to remove the oil before attempting to weld this panel in. Doing so will allow you to make a much better weld.
