is smart repair ok for noticeable areas such as the bonnet...i always thought it was only suitable for bumpers and lower down areas?
proper smart repair is for anywhere, just find a good one with good reviews,
they fill and repaint the sratch and then blend it in. never had one done myself, but i'm contemplating it for the damage i have on my wheel arch,
to be honest you just getting it to a good standard to sell. you shouldn't need to spend £500 to sort it out. this si the smae thing dealerships use to get cars ready before selling on second hand.
