I'm not sure if naming brands/distributors of paints is allowed so ill just describe by Paint 1 and 2.
Paint 1 is a newly purchased single stage red from a budget brand. I painted a bicycle frame, and a garden table. The bike was epoxy primered, sanded, and then shot with single stage red. The garden table was 20 years old and rusted to no end. I hit it with 80/120 grit on a 5" electric random orbital sander and that was that. I did the legs by hand quickly. No primer, as it was just an experiment.
Both the bike and table turned out great. Smooth paint. I had a run or two on the mountain bike frame but that was totally my fault as it was my first time using a paint gun. Zero orange peel. The small garden table looks so nice that when I gave it to my mother she has since kept it in the house and and put a decoration on it. Other than a few rust pits the rust had eaten away over time, it looks like something a fancy store would sell.
Paint 2: Twelve (12) year old unopened can of Single Stage Black. Very well known respected brand, but one of their 'fleet' lines. Prior to paint over the course of a week it spent 30 minutes in a paint shaker since I didn't know if it settled tons over the years.
When I open the can, its very watery. The lid is black, but the paint is almost dripping off it. Red Paint #1 is much thicker and coats the lid like a gel almost.
Paint 2 is 6:1:1 paint, catalyst, harder.
Paint 1 is 4:1. So I understand why paint 2 is probably thinner, as it doesn't actually get thinned as much by products.
When I shoot paint 2, it is much more difficult. Runs a little easier. Much more likely to have dry spots that don't flow out and cover. Doesn't seem to mist as well out of the gun. Doing a light coat for coat 1 is much harder than paint #1. Paint #2 when you turn material down starts to splatter more instead of misting on drier for a light coat. Heck, I even think it shows imperfections more, but maybe that's just from being gloss black.
Is this just a case of beginners luck with Paint #1 and my cheap harbor freight gun doing a better job with it? Or are some paints really that much worse to shoot?
I'm tempted to just put paint #2 aside and go buy another gallon of Paint 1 brand.
Or should I learn to adjust my gun better and figure out how to deal with Paint 2, since I'll be dealing with paint brands all being different forever?
Do paints spray/act differently?

I don't have a picture of the Black Paint #2 from today because I was so wore out from dealing with it I didn't think to even take a picture.
For Paint 2 imagine something considered almost unacceptable for anything other than farm equipment. Thank you |

Just like in another thread, that black might be lacquer. That's why it's so thin, and uses a 1-1 ratio. The other is a more modern enamel/urethane.

Yep, that's what it sounded like to me as well. ^^^^^^^^^^^ Old paint tech. versus new paint tech.....

While Black is 12 years old, it's the one with a 6:1:1 ratio. I just realized I made a typo. The Red newly purchased urethane is 4:1 not 1:1 Sorry for the mixup. |
