Spares: Battery Cover #1 Primed

Left the battery cover in Evapo-rust for 5 days (mainly because I forgot about it).  When I took it out, not only was the rust gone, but a lot of the paint just flaked off as well.  Left me with a good clean surface that I just lightly sanded, then primed.  Came out pretty well...  Would it sell for $80?
