Need automotive polyurethane, they can also match the paint color if you bring it to a jobber who sells automotive paint or bodyshop. Oil based paints like rustolum or enamels that are not harden are not very gas resistant. Look for urethane if spray can, but I don't know spray can stuff. PPG, Dupont, R&M, Martin Senoir, House of Colors, are major paint manufactors and have top quality paint, but it is not cheap. There is more people here who know spray can then I do and maybe there is a cheaper solution. Good luck on your paint job. P.S. if it lifted it must be completely removed or it will lift again
