Mike, while you are here....

Can't orange peel also be caused by water/moisture in the spray system?

I know this is highly unlikely in a closed system like one of the
turbine powered HVLPs, but on a pressure gun isn't water often a
culprit of fisheyes?


Hey Bob - no water won't cause orange peel. It will cause bubbles and
fisheye (oil will cause fish eye also), but orange peel is a result of dry
layers. You start with a bumpy layer caused by insufficient paint droplets
on the surface and as you build those up and start to generate a layer that
begins to lay down, it lays down on the highs and lows. It will never lay
down flat because of those droplets at the base of the film. It will flow
some which is what gives the orange peel effect, but it will always present
a bridging of the droplets, thus the orange peel.
