I will have to look into the PPF as haven't come across that at all so far, and I am expecting to have issues with the finish being hurt due to long hauls hence my concern of refurbs/touch ups and durability, have you had a bad experience personally with plastidip then Zippypooz as you seem quite set against it, or do you wrap cars yourself and know how good they are?
I wrap cars yes, but tried it on parts of a car and was not durable enough for my liking, but thats just my personal opinion. Ive never used Autoflex though so cant really comment on that, i know of it but have never tried it! I do know its better than plastidip though! It has a long life too if applied correctly. But personally i'd not apply it myself...unless i owned a lesser car!!
