touch mechanic

I just started and im stuck at the costum show i just dont know how to pass it i can only change rims and the thingi attached to your moter

just go to it and you will get some 20+ place and meet that other dude your boss told you about...

im stuck onepisode 14 where you have to paint onthe pattern on the side of the car ,ive painted yellow but everytime red squares comes up on outside of where ive sprayed please help am stuckkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkk!!!!!!

when red squares show up, you have to change the sprayer to the original car color and touch those areas up by spraying 2 times like normal.at the top in the middle is the new color and the stock color, its easy to correct your errors.go back to the first mission where you paint and it will teach you this.mission 10 seems to be the first bodywork mission.i am stuck at custom show 3, havent unlocked nitrous. don't know how and keep going back doing old missions.

to pass the custom shows, install everything the shop has, thats how i managed to pass the 4rth show

i had actually typo'd.im stuck on custom4 and the guy suggests nitrous, i havent unlocked it, somehow.

im am stuck on episode 14 where you have to cut them to holes in the bonet how do you do it ?
