I doubt the product is to blame for orange peels. OP occur for many reasons:

1. ambient temp too warm.
2. reducer used "too fast" (i.e. evaporates fast and meant for a cooler ambient temp)
3. gun pressure too low
4. gun fluid flow setting too lean
5. gun too far away from work when spraying

Shooting paint, like many things in this hobby, requires the right equipment, fine skills, and most important of all patience. I remember fondly the first time I tried spray painting a rear wing spoiler for my '89 VW GTI. It took me 7 tries to get it right.

Spray.. orange peels...$%*%$!...wet sanding...
Spray...runs...*@&%$!...wet sanding...
(and on and on and on....)

Eventually you'll get it right. Or you'll get disgusted, throw your spray gun away, ans swear you'd never try shootin' paint again.
