Due to a complete moron in a wagon practically running me off a country road and into the hedges this evening, I now have a lovely collection of very fine hairline scratches down the side of my new motor

.
I've been told that T-cut is good stuff to remove this kind of thing - is that true?
The car is a bright metallic, so the scratches might be only to the laquer - I'm not sure how you tell.
Also black plastic of the wing mirror is scratched to hell - far worse than the car. Any tips for this?
Frankly I 'd like to know what business a 7.5 ton truck has barrelling along at 50mph on a stretch of road where it frequently requires 3/4 of the lane to even fit...
Ah well, cheers in advance.
