I like that!
What brand of paint did you use?
How long has it been on?
Any concerns with peeling, chiping or flaking?
What did you do to prep the engine cover prior to painting?
This one will really drive the wife crazy! I can hear it now:
"What are you doing now, and why would you paint a perfectly good engine cover?"
Seriously, I think it does look good, now I've got to go find a silver color to match the Murano.
