Well, I should have known. I forgot to attach the brake fluid reservoir while the car was out for paint, and brake fluid spilled inside the gas tank compartment . Let this be a cautionary tale: given enough time, brake fluid will dissolve just about anything. After *making sure* that I attached the reservoir this time, I scraped off all the loose paint (it was bubbled up just like it would have been with aircraft stripper...) and took this photo for your viewing pleasure. And, yes, the dent there is intentional - part of slightly expanding the compartment for batteries - http://volt914.blogspot.com
