Was my first day at my new work, got there early to find no parking spaces except one in this super old tiny garage, took my time trying to manover the car into it as it was close to a wall on the oposite side and couldnt reverse in so had to fold in my mirrors and kept going in and out until 2cars turned up and i got flusterd and nervous cos it was my first day, ended up scratching my rear drivers wheel arch off the dam rough casted garage doorway! so anoyed with myself spent the whole day washing it and trying to rub out an impossible scratch with t-cut ANYWAY what im trying to say is i went to halfords to ask for gunmetal grey nissan paint but couldnt see any? is it under a diff name as there was a can that looked the same colour but diff name(still nissan) or am i better off going to nissan for it? OR should i not bother tryin myself and pay a pro to do it(how much we talking?)? HELP
