I watch videos of guys moving back and forth pretty quickly.Going over each spot several times. Metallic paint mostly.
I assume not much paint is coming out. This is for repair areas like a door and fender not a complete respray.
Seams like when they say a med to wet coat,its pretty wet.

Much depends on the gun and how it's set up and how far away from the panel it is.

Normally I hold the gun out about 150mm and take about 3 seconds per horizontal pass on a typical door. That's a bit slower than some but I don't have fluid fully open, usually, and run with about 2 bar. Devilbiss guns are usually a bit slower than Iwata while SATA are the fastest, for the same, nominal, sized fluid tip.

Practice on some paper first. You want to get each coat on evenly, but not over wet, achieving coverage in 2 coats with a quality base coat, 2.5 - 3 coats with and economy base coat. Overlap around 50%.

Drop coats usually go on a bit quicker, with the gun further back at around 200mm.

3 second per door is very slow for what im seeing.Now remember im looking at repair videos not whole car.Blending videos mostly.

The first one's an instructional video on 'how to do it'. The second is some bloke trying to make it look easy so he can get more viewers who can marvel at his abilities. Yes, I've seen quite a few of his videos and he almost never actually tells you how to do it, extending a single tip into 10 minutes of space for advertisers.

If you want a good paint job, do it like in the first one. If you want to impress your girlfriend/wife/grandson then wave it around like a dysfunctional chimpanzee.

So basically slow with a consistent overlap is better than flaying several overlapping coats.
I know this all depends on gun set up but watching different videos everyone has there own speed I guess.

From my weekender part time rookie hack perspective.
What I've learned is that I had to really concentrate on consistency, gun speed, distance to panel, mental focus, gun settings, well everything.

I still take a lot of notes on everything, mainly so when I screw up, I can come hear and tell the experts "This is what I did..." and they can give suggestions of what I did incorrectly.

A while ago I was at a custom paint weekend instruction deal and this "kid" picked up one of the Iwatas that we were using, shoved it super close to the panel and went screaming fast . I was shocked and was wondering WTH? Turns out this "kid" sprays full time and his technique was perfect - for him, not me! Anyways, I've been able to produce some pretty decent results but I bet my gun speeds are slower than most.

It is hard to get as close as most do.You just have to trust it I guess.I assume most newbs like me hold it too far away their first trys.
