Need help with photoshop please..

[siveradoss22s]

Im looking forward to painting my truck. I want it all white and I want an arrival blue stripe in the middle of the hood.. I probably would want it wide or maybe two stripes or I dont know . I dont know if maybe just in the front and to end before the windshield or have some on the roof and the tailgateor the line to end close to the third brake light up there. Can anybody photoshop these coulpe of pics for me.. I have the Gmc front on right now but would like to see both gmc and chevy please.

would i have to go with a stripe parralel to the lines on the hood or can I make it closing in to the grill..
