I have pounded out a smashed and creased front drivers fender and am getting ready to maker pretty. What body filler material do you guys recommend? If it were any other rig I'd just use bondo but POR-15 makes a "special" filler that blah blah blah. I plan to use the POR products inside the fender well and all over the place anyway so maybe I should spend the extra few bucks. Let me know what you all do. On a side note I have a hole in my tailgate and want to patch it. It started out as a puncture but then rusted around it. I am thinking about tacking (MIG) a piece of metal on the inside and the filling it in. Any suggestions or comments are much appreciated.
