Body Work Expertise Needed

Well there are two camps when it comes to body filler. Some body guys will only put body filler (I use Rage) onto bare metal. Some will tell you that because body filler absorbs water that that is not a good thing to have right on top of bare metal (promotes rust) and most good epoxy primers will tell you in their tech sheets that you can put body filler over the top of them with no difference in adhesion properties vs. bare metal. Some people say potato some say pahtato. Who knows, go with what you are comfortable with.
