I like the final look your after - the tints set it off so well. I love punto's in a deep blue - allways looks good. Better than the metalic mint green mine has
I am tempted to re-spray it but there's not much point, it would cost far more than the car worth
im giving it a full respray once the parts are fitted but proper garages charge around £1500 for a full respray and i dont really fancy spending that on paint id give it a go myself for that type of money
