What's a good starting point with air pressure on an airbrush?

It depends on the paint and how thick it is.

 

If you're using water-based paintt I would start with 50 lbs of pressure.
If you're using lacquer-based paint you can use about 20 lbs or less of pressure.

 

Also if you use that water-based paint you need to use the tip with the biggest opening; l use the 0.5mm tip.

For Parma paint I start with 40 lbs. For fine work, I use 60 lbs as a start and go up and down from there.

 

I was just teaching my son last Friday and for Pearl green we went up to 80 lbs. That color seemed really thick. This was with a gravity feed brush. Try differant stuff. The first ones you did look great.

I usually start with air pressure at about 25-30 lbs – which will drop significantly when you begin spraying. I use Createx and/or Faskolor and thin it to about the consistency of skim milk and use a 1/6 hp compressor from Harbor Freight. If I was painting professionally or even doing more bodies than I do, then I'd have something a little higher grade. But what I have has a regulator, pressure gauge, and a moisture trap and serves my purposes.
 
Eddie (Nathan's grandfather) has proven that it's possible to do fine lines and shading with water-based paints just like when we used lacquer if you get the paint consistency right.

Thanks to all for the replies. I have been using the Spaz Stix paint. I like kebit so far. The hobbytown store up near Tampa don't have a big display of colors, I only have about six different colors so far.

I did get a color change and the crome paint. I tried to post a pic of the crome body I did, but I can't seem to figure out how to post a pic in a reply on my phone.

Here's the only 1 I did with the crome or mirror paint. I also retire to use the color change paint on the flames on the hood, it came out looking like ghost flames. Cool looking but that's not what I wanted.

I think it looks pretty cool.  I love ghost flames on hot rods.

 

Johnny Banks painted some cars with Alclad's Chrome paint and they looked good.  Someone at our track tried another brand and it just looked like a slightly shiny silver.

Hi Brian

Looking Good.......

 

I find if you use the color change ....... spray on lightly.... when you can see a little color STOP!! TOO much and the color

looks washed out..... Also Back it up with black...... Color WILL POP !!!... Also back up your Chrome with Black....

YOU WILL LIKE !!!!!

Keep it Funky !!!!!!

The pic don't help the paint on this car. It looks better in person. I did back both the crome and color change with black. I don't think I shook up the paint long enough. Just a couple shakes and I poured it in the brush bottle.

I'm going to try this weekend a different idea. I'm going to use eithe candy purple or blue very very light then back that with the crome. I'm going for a crome purple or blue look.
