All great questions. I will try to help but hopefully others will chime in. My understanding is that the yellowing that occurred was largely due to the adhesive used and the newer manufacturers which includes Suntek and I believe XPEL went to a
UV resistant adhesive*. Most of the PPF companies will warranty their product for 5 or 10 years but be cautioned these companies have more loopholes than one can fathom so in many cases the "warranty" is just a piece of paper.
1. From what I read white cars are more prone to yellowing especially with the old non-UV resistant adhesive.....not sure why except maybe it's more apparent
2. Newer manufacturers should not be a problem but I have used mostly Suntek but, in the interest of full disclosure, I have moved in and out of cars pretty frequently
3. The yellow with the old adhesive was sun related so again the new adhesive* should solve that but garaging and cover, mostly garaging the vehicle will slow the yellowing process down for the old adhesives
4. That I can't help with except to say although the adhesive is improved* it's still a plastic so I want to see what others that have had their supercars for a while can say but, again, these people with the "older" examples may have the non-UV resistant adhesive.
I would probably go with Suntek, and a word of advice, don't be overly comforted by their "warranty" they have more excuses, when problems arise, than a criminal going to jail.
