Painting dilemma (long). What would you do?

i am completely self taught DIY painter, you cannot go into it getting frustrated your first, 1, 2 or 3 attempts. Hell the first car i painted i had to redo multiple panels over and over until i got them right. Starting out, honestly i found single stage more difficult then a 2k process. Hell i started paining on hotwheels with an airbrush, i know, its a completely different level. but taught me overlap and control are the most important thing. I would definitely step up filtration, and the little water separators you attach inline with the gun just dont cut it.

dont expect perfection without perseverance and practice. overlap and gun control, especially on long overhead panels. was the hardest for me to learn. especially spraying long roofs bent over, with 600ml of paint. If you dont plan on building some type of enclosure, you are going to get dirt in your paint, fisheyes, many random imperfections. you either accept that its going to happen or build an enclosure. If you call around some shops may rent out booths to you, it wont be cheap. but it is an option.

Again, i am no professional, by a long shot, and i know i do things wrong. but if painting is something you want to learn, like anything else, you will make mistakes and learn from them, and press on.
