If you can’t feel it with your finger nail then it will polish out without trace using the correct cutting compound - normal finishing polish may not be sufficient but worth a try.
Even fine scratches that can be felt can be removed with a medium to hard cutting compound and then finished off with a super fine polish.
The only downside is each time you use a cutting compound you take away a little clear coat, so you need to be careful, but if you can’t feel it then it won’t take much to polish out.
I removed multiple fine scratches from my Lapiz Blue MK8 R before I sold it and I was a complete novice with a DA Polisher. They are a great investment.
Agree that a DA polisher is a good investment - mine has paid for itself many times over. I used it to polish both of my previous two cars; I was also a novice but I thought the results I achieved were excellent - probably not quite up to the standard of a professional detailer but then I saved myself the cost of paying professional detailer prices.
I’ve not tackled a full machine polish of my car for a few years now - not due to lack of care or enthusiasm for my car - more a case of my ageing bones and back problems, which means I suffer for quite a few days after doing a full polish. I have used it for spot polishing though to remove bird poo etching, the inevitable swirl marks on piano black trim and some scratches on my brother’s car. He was impressed as he thought he’d need to get the scratched areas repainted.
For anyone who’s into car detailing and likes gleaming paintwork, IMHO getting a DA polisher is certainly worth considering.
