I'll throw some input as far as the CQuartz finest, I had it professionally done from a registered dealer for reference. As far as cost, I had to have paint correction done first, which included wash, decontamination (ironx, tarx, claybar), and 1 stage polish. So, the CQuartz install for me, which included said paint correction, cost me $600 (USD not CAD.)
If you want PROTECTION, don't get anything other than a film protection wrap, a wrap is the BEST way to protect you paint from rock chips, tar, everything. Neither CQuartz finest, nor any other coating
will protect your car from rock chips.
If you want to have awesome looking paint, that's super easy to maintain, but you can handle getting rock chips from time to time (ya know, its just a car), than save your bucks and get a coating.
Also, those are some seriously steep prices on the PPF. The business I went to here in NJ (4.9 star rating) had a Ferrari 458 that they had just finished a full body XPEL wrap on, and man did it look good, couldn't even tell the film was there. I got to talking to him about it (because I was considering the PPF, but I just couldn't justify the price on my car).
Obviously this is word of mouth, but he said he only uses XPEL because it's guaranteed not to yellow for 10 years, it's easy to work with, and it just comes out looking freaking amazing. Anyway, the price he quoted me for the CR-Z was $1100 for impact areas, and $2,200 for full body. I hope you can find a better price for the film, because if it's the car I think you're getting, you're gonna want to keep that baby looking pristine.
Good luck man! The hardest part isn't choosing which type of paint protection to get, it's figuring out how to pay for it!
