   As long as it is surface rust, no problem. I've used phosphoric acid on   
   rusted motorcycle tanks. It is a frequent enough problem that there are   
   kits available like

   There are also latex based sealers that have mixed reviews:

   and-liner-1-quart-g.html   
      
   or epoxies:

   Personally I use standard hardware store pourable epoxy, the thick kind   
   made for coating bar tops or decoupage projects. Do not use the cheaper   
   polyester resin.
