Yesterday we beat and banged on this Ford F150 until we mostly knocked the dent out. We also had time to get some body filler over the repair to smooth up the repaired area and get the tailgate sanded smooth.
Today we sanded the area under the tail-lamp and got both spots, the area under the tail-lamp and the tailgate, in primer. Primer is used to seal the body repair underneath, to protect it from the elements and thus prevent rust. Primer also provides a surface so that the paint, when applied, has something to grab onto for adhesion.
Now that the truck is ready to paint, we just have to find an open slot in the paint booth schedule.
