Was wondering what others have done to the inside of their car or truck doors to restore them.I got a pair of 70 Duster doors to replace the 73 doors somebody put on my duster.Surface rust on the inside of the doors.Would be hard to sandblast the rust away.I live too far away from a company that would dip them in a bath of chemicals to remove the rust,plus the cost factor.I am considering blasting the doors the best I can on the inside and then coating with Por-15 or Rust bullet or similiar product and going from there......Any suggestions?????
