Your asking the wrong ppl. Of course they are going to say that. It's like going to a wood flooring supplier and asking if wall to wall carpet is a better idea.
Dude, it's the exact same paint. It just has more hardener in it so it can dry super quick. It's a skillful process. No repainting is perfect whatever app.
Naturally, Auto body guys want to paint the entire panel, it's good money. For example, metallic paint by virtue of the laws of science, never perfectly matches because the metallic fibers in the paint set up based on the magnetic field surrounding the car at the time it's sprayed. Consequently, in sunlight the exact same metallic colour, but from two different apps, can refract light differently. Follow that?
Go to any dealer that does not have an autobody or a financial interest in one and ask for the number of their mobile paint guy. Maybe he will come to your house or office. On a clear day over 60 F he can do it outside sans wind. I've seen it done outside with snow flurries, almost.
