I am working on a project that was completely stripped to bare metal. I got to the point of etching primer, body filler and then sandable primer. While sanding the primer, I found some areas (ok poor metal work by me) that sanded throught to bare metal.
Is it ok to shoot etching primer over gray sandable primer? to cover the bare metal?
Or what is your suggestion? simply shoot sandable primer over the small bare metal spots?
