I shot my first single stage yesterday and I'm real happy with it, But it opens up a ton of new questions for me to bug you all about. The one that really has me wondering is I got a lot of overspray on the gun, cup, hand etc. is that normal? I was spraying in a garage with little air movement which probably contributed to the problem but this seems excessive to a guy who has never shot this stuff before. I should have got a pic for reference. I'll have better air movement next time.
I was spraying Motocryl at the recommended 2:1 +10%, 2.5 turns out for fluid. 26psi fan one turn in from wide open.

Here's a couple pics, If you disregard the trash in the paint, I think it looks good.

Another thing I'm curious about is I got a static shock a couple times while spraying, really not something I want while in an overspray environment. Any suggestions on why this happens?
 
Pretty sure that is normal if you don’t have any air movement. You are in an overspray fog and it will stick to everything.

Can’t comment on the static. Maybe ground your work with a ground strap.

Looks good Dan.

your likely blowing out the middle of your fan. very few guns can shoot wide open. no mention of what gun but excessive dry build up on the nozzle is sign of dry spray . adjust your gun .
 
I'll give all the credit for the shine to Automotive Art, and it covered real nice in two coats over reduced grey epoxy sealer.
 
You need some airflow. Painting in a cloud of over spray is not healthy for you. your paint job or good for your shop.

Overall it looks very good. Same settings I use on my LPH400 1.4 when shooting SS and Clear coat.
 
Does look good.
ALL that cloud,overspray,etc is MONEY WASTED.
Is how I think about IT.
Gun Adjustment is something so simple and SO Ignored.
With that lph you should be putting the Money on the project not up in smoke. I watch painters who
"I run the fluid at 3 turns or wfo and the Fan is wfo.I use my trigger and control everything,blah,blah"
and Their spraying like madmen whipping all over and around all the time standing in a fog.
With 2 Minutes of your Time,A vertical piece of masking paper,I prefer White,you can adjust 2 knobs,slow down and do a Lot less sanding and buffing.

Agreed with paper on the wall. You can see the difference in fan sizes from the LPH to the DeVilbiss Tekna Copper.
Once I get the pattern adjusted and it's shooting the way I like it. I write the settings down in a notebook. Saves time getting the gun set up for the product you are spraying. I still shoot one test pattern on the paper before putting any on the vehicle.

That pattern should provide full coverage, no blank areas, and the droplets should be fine throughout. Absolutely no runs allowed.

I always hang a chain from any car I am painting just for static. Don't know that it helps but was told to do this many years ago. With individual parts it's harder to do. I do know that I am in a high humidity area now and have almost zero static problems. I use to live in the panhandle of OK/Kansas where it's dry and the wind blows all the time. Lot's of static in those conditions.

Now I just have a lot of water to remove from my compressed air! I do love my refrigerated air dryer because of this.
