Hello,
I use various guns, mainly mini-guns along the lines of the SATA mini-jet and Iwata 101`s. Airbrushes are great to use and can be used for both Opti-Seal and Opti-Coat.
I airbrushed some Porsche interior pieces today so they are very versatile.
If I am using a mini-gun I will use around 20 psi, with the fan open to spray a nice wet application the first go. When spraying Opti-Coat or Opti-Seal it`s not like laying down base coat/clear coat where you want a nice wet coat then let it tack up before a second coat. I usually spray one wet coat over, say a fender, then move on to the door, etc.
Now an advantage the double action airbrush has over a mini HVLP gun is you can blow just air over the area you just sprayed your opti-coat aiding in setting and curing. I spray my airbrush around 40 psi.
Also when I say "wet" coat I don`t mean to the point where it runs or puddles but to where a nice even wet sheen is layed down and then begins to evaporate away in quick manner. Now as for the new public version I have not sprayed that so I am not sure of the reaction time. Experiment a bit on your own.
I may get 2 cars out of one syringe, depends on the size of the vehicles though. Lets say 2 Porsche 911`s.
I do try to mask off areas I do not want the coating on, such as glass.
When spraying you`re getting all the actives to the paint which in turn gives you greater, in theory, adhesion and protection. The look, you may notice, shall be different also. You may also notice that you won`t need to "knock down" as many high spots versus hand application.
Some people may claim that the spray version is more complicated which may be true but I just like being a bit different
I will, if I get the time, film and post up a video of my methods both by hand and spray gun.
