The orange peel is a paint defect and unfortunately we can't do anything about it at large, i wouldn't advise consumers to get their car compounded in order to remove the orange peel, a slight pressure spot and poof goes the paint.
As to the fact that even after glass coating it has swirl marks; this is a classic example of dry dusting. Clearly supports the point that glass coating won't help against swirl marks or bird droppings if not properly maintained.
No matter how thick a layer or whatever paint protective material you put on the car, dry dusting will ruin everything for you.
I remember the time when i was taking delivery of my 9th, i was dreading the cleaners at the showroom cleaning it with rotten cloth, ended up with so many swirls on the new paint, had to layer it with waxes to mask the swirls.
Eventually corrected them with a hand application of polish.
