WOW it's been a year... where to start and how to help??
First, make sure your airbrush is cleaned out. Tear it apart and give it a good cleaning.
Second, you NEED a pressure regulator to adjust the air pressure coming
from the compressor to the airbrush. Once you have that hooked up and
your airbrush is cleaned and back together.
Test your system by spraying just water through it with an air pressure
of oh say 10 - 15 psi. It should spray out smooth. Then try adjusting
and spraying at different air pressures (psi) by adjusting the air
regulator.
Hopefully somebody here knows if the Whirlwind 2 compressor is up to
handling the Badger 150... you know, matching cfm @ psi usage... ??
