@ xulfiqar...one of my friends has a daewoo racer, it's bonnet was remade using loads of filler, now the actual metal skin had gotten weakened, when the guy closed the bonnet, the skin moved a little and there you go, the filler fell off
btw i think that a suzuki 3s dealer might be able to provide a brand new bonnet with primer, it will just need to be sprayed in the car's colour, if you can find a painter who is good with sand paper and compound he can finish it nicely so that the orange peel isn't too bad, it will blend better with the original paint that way
