Texture questions

I sprayed SPI, for the first time the other night. Really my first time to spray any sort of product I cared about (lots of old work that was complete crap, and bedliner stuff for my Jeep).

I spent a ton, way more time than I thought I would with the W&G remover and rags, got it all spotless as best as I could tell. I sprayed with a husky HVLP, not sure I had the settings all set up perfectly as I don't have a regulator gauge at the gun. But i sprayed well and came out pretty smooth.

However, and here is my question. On the firewall I am planning leaving the black epoxy as my finish coat. The attached images show it is just a bit bumpy. I suspect two, maybe three things are at play.
1. Maybe I didn't spray wet enough or overlap enough? I was spraying just enough to not have dry stripes between rows of paint. Should I be overlapping more?
2. Perhaps gun was not setup well enough. I am going to pick up a HF purple today for primer. Then a nicer gun in the future for base/clear.
3. Could also be depth of spray field, I was shooting tip to panel at around 12-15", it is a bit difficult because cab is on it's back and the firewall is about 5' high and laying flat with the varied edges and angles of the tranny tunnel etc.

Of course it could be, this is the best it gets, but I suspect it is just because I am a novice. I still need to apply filler so sanding is to happen tonight/tomorrow and a hopeful finish coat of epoxy to be sprayed on Friday morning

I did. However, being a novice I had zero reference points to know what was good/bad/etc. I adjusted the gun out to both extremes and settled somewhere in the middle when it looked right to me, so could have been just a bit off.

Shallower shooting depth, and mover overlap. Got it. Thanks
 
I'm no painting expert, thats for sure, but it kinda looks to me like it could be in the metal. Sometimes you don't notice something until it gets some shiny paint on it.
 
Hold the gun at the proper distance and perpendicular to the paper. Squeeze the trigger full open for 1 second and let go.
You want fine droplets throughout the pattern, no runs, no drips, no dry spots. If you cannot get the droplets small enough up the air pressure on the gun and try again. Time spent adjusting the gun properly is time well spent.
Once you get it good on paper try a short pass on the panel. You may need to adjust the fluid control out a bit depending on your painting speed.
 
You'll want to do your filler work and finish it off well, shoot two coats of epoxy then sand it again w/320 or 400, then shoot your final two coat of epoxy. It will be slick if you can dial in your gun adjustment and application. 50% overlap 6-8" from the panel, it should go on wet but not wet enough to puddle-watch the primer how it goes on within the spray pattern as you spray.
