Learning how to make your paintung look good by painting it yourself has to be a hard row to hoe
I tried painting two large under the bed tool boxes on one of my car hauler trucks years ago, I bought all the good stuff at that time including a Binks #7 stray gun, I didn't know that each coat should be sprayed on heavy enough to shine but not thick enough to cause runs They look like they had been painted with low gloss or flat paint along with a couple of runs
No more painting large surfaces on cars or trucks, I'll take it to the better auto body shops locally to get good result for my projects
I do envy those that develop the talent and skills needed to be a good vehicle painter
I do paint all of my engines I build with spray cans with decent results
