Thanks Donkey… I'll help the best I can……
1) If he was a "pro", then shouldn't he have noticed the scratches and at least offered to polish them out before applying the OCP?
Unfortunately I had the exact same problem when I had the dealership from my last car "professionally" apply a coating. I was shocked that they didn't bother to even offer to polish out the paint BEFORE applying the coating. I assumed that they did that already and that was part of the package….NOPE! They didn't even bother to offer which is what REALLY irked me and so from that point forward, I knew that i couldn't trust them and so I decided it would be best to "learn" how to do it the Right Way and save $$$$ in the process!
So to answer your question, you can either wait the two years or so it takes for the coating to start degrading and wear out, and then polish it……OR…… You can simply machine polish through it now, do the corrections on just that one panel, and then just re-apply it yourself.
You may not be able to get Opti-Coat Pro, but Opti-Gloss coat is available to the public and is the same to apply and is easily just as durable since they last the same amount of time. Cquartz UK is another great coating that has the same life expectancy on a vehicle…all of these usually should last for up to 2 years. but this has to do with how YOU take care of your paint within those two years!!!!!
2) Yes, absolutely! I covered ALL my Trim & Wheels with Dlux. This stuff will keep black plastic cladding looking great in Any weather for up to a year and repels not only water but dust and dirt too unlike dressings. Highly Recommended!!!!!!!

4) I would not recommend putting any kind of sealant or wax on top of a coating. For one, the sealant won't be able to bond to the coating like it would be able to with a clear coat, and two, sealants attract dust and wear out very easily compared to a coating. Sealants don't help coatings in any way, shape, or form.
ONR is great stuff….. I would also recommend getting a large bottle of Carpro Reset as it was designed for coatings specifically ….. this stuff will REALLY make your coating shine & pop.
If there's anything else….don't hesitate!
