Its a cheap ebay one, as it is my first go I didn't want to spend heaps. If all goes well I plan to buy a brand name. Its duel action with three size needles so it has everything I need to try out on.

It seems to measure the psi off the tank and not off the psi entering/leaving the airbrush. I guess I have to wait for the gauge I ordered, I expect a couple of weeks minimum wait as its coming from hong kong.

I used cheap art acrylic and thinned it with the windex, I will try thinning outside of the cup with water and see how this goes. As you said, practice and questions. I will keep trying it. I used this paint as I didn't want to practice with expensive paint. I have some lessons from online that are basically practicing techniques on one of those massive cheap art books. I plan on practicing with this. By the way, I looked at the card I practiced on and the blank side which had no paint on it prior to the test looks quite good. It just took a long time to get enough layers down make it dark.
