We have quite a few car gurus on here and I'm wondering how you guys prefer to fix minor paint blemishes?

I've watched many youtube videos on this and am looking to fix up a few little marks. The car is black with a pearl in it, Nighthawk black pearl to be exact. I've tried factory matched touch-up paint from the dealer but frankly, the results suck. It comes out looking uneven and lumpy and this texture makes it look fairly obvious.

Is there a way to smoothe out this lumped mess and make it blend in? From the videos I gather that you would use a 2000-2500 grit sandpaper and smoothe it out, follwed by buffing with a polishing compound, and finishing off with a good wax/sealant.

In theory this sounds fairly simple, but the thought of possibly doing irreversible damage has me a bit hesitant. I have asked around but do not know anyone personally who has experience with these type of repairs and youtube videos aren't always very trustworthy.

In short, I have small touch-up paint marks on my vehicle and would like to blend them in. What is the best way to do this?

Thanks for reading my ramble, all help is appreciated.
