Can you tell me more about the "look of it in a few years?" Also, I'll be getting a full prep/paint correction at the dealer and the OC Pro will be fully cured for 24 hours before it comes out of their facility.
OC is a permanent coating, so if it gets scratched, scuffed, or if "exposure" (environment or man produced contaminants) renders the OC not as effective (as a sacrificial barrier) or if something comes to affect the optical qualities, then you will have to compound it off.
The look, the feel, the protection qualities are all dependent on the maintenance you do. You cannot expect to put OC on and just neglect the truck, because the paint will suffer the same faith, regardless of the protection. The OC is not impervious to the etching problems of water, bug guts, bird bombs etc... and will not prevent the bonding effect of paint overspray, rail or brake dust, tree sap etc... You will still have to wash and decontaminate the paint (clay or clay alternatives) when needed. You will still have to use proper washing techniques (and you will still want to avoid car washes) to prevent inducing scratches and swirls.
Before the argument is made, YES in certain cases OC is more resilient than the clear coat it protects (I'm thinking about the infamous soft clear of a black Porsche), but in most case it is the same or in the case of single stage white paint, a little softer.
OC is a sacrificial barrier, same as the temporary products I use, but it does not mean that you can just send the lamb to the slaughter house. It does have the convenience of not needing to be reapplied, but does carry the cost and the inconvinience of compounding if it needs to be redone.
I just want to throw this out there, in the maintenance of my truck, it is washed every 2 weeks, gets waxed quarterly, gets clayed every six months (or so) and gets a light polish to remove light water marks and fine scuffs and scratches once a year (.....IF needed....). The only time saving you have over me is the 30 minutes it takes me to apply the paint sealant every 3-4 months. You still have to wash it, clay it (when needed)....
The OC application is normally done after a good prep which includes a polishing to remove as much of, if not all, the clear coat imperfections. Cost varies from state to state and if it is a new vehicle compared to a used one, but regardless the compound and application (and product) is not inexpensive. Spot repairs are possible but very tricky. On my truck, no worries with fixing a scuff. I polish and reapply the LSP.
24hrs is a good flash time but OC, even OC Pro can take up to a few weeks to cure. You will see what I mean when you touch the truck. It won't be a rock hard surface (initially). During that period of time..... BE CAREFUL!
