Paint sealer

Depends on the definition of 'paint sealant'.
If it's the addition of something at the dealership, my advice would be to go gamble the money away at a casino as you'd have a better chance of the money being worth something versus spending it on the 'dealer option' of sealant...
Now, if you're talking about a product like Zaino, Klasse, or another 'sealant', it's probably worth it...
As for it preventing swirls/scratches... no, not really. It will provide surficial protection and can take the blunt end of more abuse but prevention is not a word that I'd utilize to describe a sealant... protection yes... prevention of scratches no.
