I have to have my car ready for primer by the time my dad gets back from the caribbean on the 21rst. Today I bought 1 gallon USC FR1 Featherite bondo and UPO 714 Dolphin glaze self leveling polyester finishing putty to put on top of it. Do I just sand around the dents (beginning with what grit and finishing with what?) apply the bondo, and then apply the finishing glaze? Then sand to 320 and wait for primer? Any tips/suggestions?
