I used to be really terrible at painting White paint.
That was a very big problem for me, since I like the Light Gull Gray over White USN aircraft so much.
So, I hunkered down and "got it right" and painted White enamels with my airbrush.
Then I switched to Acrylics, and had to master it all over again,,,,,,,,,,,,but, the good news was that I already knew a bunch of ways that wouldn't work, so getting Acrylic Whites right didn't take very long.
That puts me in the position of liking every aspect of model building,,,,,,,except I can get a bit put out when I find that I need to sand and fill for three or more tries before my model is ready for painting. But, even then, I know how to do it, and don't really hate it,,,,,,,,I just want to get to the next stage, lol.
