hi, dont know if this is the right section to ask this question if not sorry.
I'm in the process of fitting a 7" screen in dash, got a double din fascia and cut the monitor housing to fit inside done some bondo work but i'm stuck on paint.
halfords do a rover gunmetal grey i was wondering if anyone has used this if so how was the colour match.

work so far.
pic 1 monitor housing stripped and cut
pic 2 standard double din fascia
pic 3 fascia with housing inside
pic 4 monitor bezel after some cosmetic work carried out (sorry pic little on dark side took .late at night)

a couple more days of fine tuning and paint (got to find a match with dash, help needed here) and it'll be ready to go in
