1st 2 hours of owning my first skyline, it was delivered to my house off the truck and was filthy as... about 30 minutes i took it for a drive down to the local car wash.... rinsed the car and the brush then checked the paint over... wasnt too bad... gave it a wash and then noticed LARGE and deep scratches in the roof... must have been a stone lodged in the brush somewhere where, possibly up near the plastic bit.
Seeing as it was on the roof i never bothered fixing it... gave it a polish and it looked better but was still visible.
