Oh well I thought it is something worse, you can't blame children for this, they simply adore forbiden things. But I think you will be able to fix it (super glue do fantastic things

). I am only sorry that you want be in contest (or maybe you will, if you took some finished car pics

)
My kid is still very small but I am shore that he will "kill" some of my models to, but that's life. (and life sucks

)
