Great pics of your Maxima. That black is very shiney and deep.
However, I'm sorry to say that putting Xpel (i.e. clear bra, 3M Scotchcal, Stongard,etc.) over that type of damage is really futile. The film only accentuates the defects. This brings out the importance of installing the clear bra film EARLY in the car's life.
As a 2003 Maxima SE owner, I can sympathize with you. You're no doubt aware of the huge discussion on maxima.org about the paint chipping problem. I installed Xpel on my Maxima with less than 100 miles on the clock. Best investment in the car I've ever made.
Here's a pic from maxima.org about how severe this problem really is:
My 2002 WRX has now had the Stongard kit for nearly 3 years. Not a single chip on the front end:
Even my garage queen 350Z has the Xpel kit:
