If you don’t paint all the way to the lip any paint should work . Occasional spills won’t do much if you clean it off quickly just like the body . I do motorcycle tanks often the problem is when you have a paint edge to close to where the fumes are present . The gas gets under the paint and softens it as it never really dries . If you have ever filled a motorcycle you will notice where the rubber on the cap seals there is no paint .
