That black R35 GT-R will be a piece of cake to work on. I just detailed a 9 year old S15 that has never been detailed before. On top of the deep scratches from people leaning on the front left guard, there were swirls galore, paint fade from being out in the sun, acid damage from bird poo, you name it, the car had it all.
The paint correction process took me almost 10 hours to perform, but in the end, the client was elated with the results and costing half the price of what Eurogloss would charge. I must say, I'm no Mario but I can do a job just as good as he can.
