Painting aircraft
Was always a mystery concerning the application.
then spend millions on upgrades then closier (strange but true).
most coatings in todays Aerospace industy are cancerous though
yes isocyonates in them all
The worst being those with yellow cromeates
But no matter what paint you atomise weather it be the old cellulose, polyurethane or household emulsion ,
as soon as you atomise any of these products it becomes harmful to health.
Hence there reasoning to apply by roller.
in todays market they even have what they call safe paint remover you could bathe in it and it wont burn the skin ,
but applied to the surface of an Aircraft it takes everything down to bare metal.
Still you have to wear breathing aperatus.
I used to work for a German / American Aircraft manufactorer,
we used electostatic all the time but even with the equipment in full working order the paint atomisation was still like fog.
A fantastic methord but not always suitable unfortunately
But the spray guns on the market are all mostly high volume low pressure ( less atomisation)
Whatever, it is still an unhealthy job and you either love it or hate it.
