Very nice pair of tanks . No rust on the inside. There are some small dents . No bondo. They were primed over bare metal with red oxide prime like the factory and painted black .There is nothing under the primer and paint but metal . They were made to look old . The red oxide primer is showing through in some spots .There is some light pitting on the OUTSIDE front of one tank.$3500.00 Dan 9one3 5one5 372one email me for picture D6400LATgmail.com Replace the word AT with at sign.
