Photoshop request ** grill

hey wondering if any of you photoshop types wanted to do somethin.
I was thinking of painting my grill silver like the rest of my truck.

so heres a pic, just where the red arrows are is where I want it colormatched silver. I tried but it looks horrible lol no shading, shine, etc..
on the bottom grill, just the line going across will be silver and on the top grill if possible keep the black circle around the toyota symbol.
if this looks how I m thinking, this will be my next project.
oh and the finished picture doesn't have to be my truck. If you have a better shot of a silver truck use it.
thanx
