Can I slow down or prevent clear coat failure with PPF?

[91RS]

I have a bit of an odd question. I messed up and bought this 2013 Escalade knowing the roof and hood needed to be repainted. I thought I looked it over well enough and didn’t see any damage on the rest of the truck, specifically the tops of the doors, quarters, and fenders.  The truck is metallic black, was slightly dirty when I looked, and the damage is so small that I missed it. I washed it the other day and found some very small cracks starting in the clear coat on the top of the right front door, one corner each on both rear doors, and after I buffed one quarter as a test found a couple cracks on top of the quarter. I bought this truck to be the family car and it won’t be garage kept since it doesn’t fit and because of all the other work it needs, I’m not really wanting to spend $10k on an all over. I’m willing to get the hood and roof painted since I was planning on that when I bought it. So I had an idea to wrap the tops of the quarters and tops of the doors in PPF to hopefully stop or at least seriously slow down the deterioration. I don’t need this truck perfect but I don’t want it shit either. If I can stop it where it is and/or keep it from getting real bad for a few years, I’ll be happy. So that brings me to my question. 
 

Is there reason this may be a bad idea? Will where the clear coat cracking cause any outgassing and air bubbles? Or worse, will it be like a green house and speed up the deterioration?

If you move forward on the idea of overlay the deteriorating clear coat areas (top of door etc.) with PPF and it does not go well short or long term, removal is going to be ugly.

If you are going to repaint the hood and top, why not include those areas mentioned in the repaint. Certainly a body shop can segregate according to bends in the body and paint everything above those lines (however mild of a bend they may have)?

Because there is a significant price difference and because it’s metallic paint there’s a risk that even the most talented painter won’t be able to bled it perfectly. My guy quoted $350 for the PPF and I haven’t gotten a quote yet from the body shop I’d like to use but another buy shop quoted $200 per door top so that’s at least $1200.

$350 is expensive to do the tops on 4 doors and 1/4 panels on a long wheel base SUV? I thought it was pretty reasonable.
