I'm re-installing some door seals on a 78' Lance and am looking for some recommendations on what to paint the flat part of the door that the door seal sits on. It looks like there will be a little bit of the door visible between the interior trim and the edge that I'd like to paint. Since it's such small area I'm thinking of using some sort of aerosol can. Any recommendations on a good aluminum primer and paint brand? Thanks in advance for your help!
