Paint over Bondo

No kiddings, a friend of mine had his 68 camaro redone paint and body about 15 years ago. car has been barely driven and garage kept, the paint cracked and chipped near the wheel well. I told him " keep those chips and crazy glue them on, hit it with clear, wet sand and buff..." the chips are big, quarter size. hes upset that it didnt last I said" this stuff happens sometimes..."
