I saw your thread on DW, do we know if the newest C1 formulation would last this same amount of time? How is your car used and stored, also a guess at how many miles it's traveled in those 4 years?
I actually did this yesterday. I polished half my dads car last weekend then half this weekend. I applied PNS to the hood/top/trunk and passenger side. After I finished yesterday I re-applied PNS to the hood/top/trunk again along with the drivers side of the car.
If you were going to top the coating up every 6 months, wouldn't you have to buy a new bottle every time? Pretty sure I've read EXO v2 is only good for about 2 weeks after opening.

I noticed my moms car this weekend was suffering from the pollen, it has Sonax Polymer Netshield on it. If its not pollen season then its love bug season down here! It never ends!
