Concerning SETTING THE COMPRESSOR AND SPRAY GUN SETTING:
typically automotive paint and clear coat requires AROUND 30-40 psi (pounds per square inch) coming out of the compressor going into the gun.
Check with your paint supplier to get the exact recommended psi for your paint.
Coming out of the gun nozzle this ends up being around just 10psi.
So, how do you set things?
The gun output should drop to 35 psi AS YOU ARE HOLDING DOWN THE GUN TRIGGER and spraying–
you’ll spray on a piece of plastic or cardboard to test and adjust.
When you are not spraying, the psi dial will be slightly higher on the tank.
Pressure drops a bit as you spray.
As it comes out, it is actually 8-10 psi, but going into the gun per your gauge reading, adjust as above.
the pressure coming out of the tank will be 35 psi at either the tank outlet or before the gun AS YOU SPRAY–
make sure this is what it reads
The tank gauge when not spraying will only be probably 40-43psi
if you have the same husky tank as I do, there are two dials and one knob on the compressor
The knob sets the pressure out– and you’ll set it at about 42 or so–
Look at the output gauge as you spray– it should drop to 35 as you spray– if not, adjust the output psi so that it does register 35, or
the recommended paint psi for your brand of paint.

THE REAL SCOOP ON PAINTING YOUR CAR
The reason I learned how to paint a car is because I owned a rare collector car that would have cost me $3000-$4000 minimum to have the body work and paint done- and it needed it. AND, I could not afford this.
So, I contacted one of my friends, perhaps the best expert on fiberglass repair and body painting anywhere, Mr. Vic Cooper in Denver. He regularly repairs and repaints the most expensive, the most exotic passenger and race cars, from Lotuses to Lambos to hot rods. He taught me how to do this over a long period of time. Since I am a writer and film maker (and he and other experts I knew are not), I translated everything I learned from him into a form that people could easily learn from right off the web. I further got regular advice from an exceptionally good paint shop in Denver that specializes in automotive refinishing.
I spent months learning what works, and what doesn’t work- and when I was done I had done my first car, my white Lotus on the book cover. It turned out perfectly. And the method I used can be applied to any vehicle, fancy or plain, big or small, boat or car, truck, bike, or motorcycle.
There are tons of BAD books and DVDs that look good on the surface, but in practical use were complicated and had stuff in there that was unnecessary. I wanted to make material available that WORKED as advertised, and was not overly complicated or poorly written.
You may find yourself in a similar position looking at painting your vehicle- but without having done this previously, or have done it making many mistakes and not having things turn out so good. You may not know anyone who knows how to do this, or has the time to show you.
I will show you, because it is my business teaching people- and I’ve been a teacher for 35 years.
If you decide it is best to paint a car yourself, you will need a spray gun, a compressor, the paint, some miscellaneous small tools, sandpaper, and a certain amount of patience. Do it in a car port, garage, paint booth, or even in your driveway- Decide what is best for you.
You can borrow or rent the gun and compressor and save money that way, and pay about $100 for the paint and sandpaper, and if you read the instructions you can come up with a decent paint job on most cars. You will also need odds and ends which you may or may not have, light solvents, gloves, an air respirator, and other small items necessary for painting.
Or, you can spend about $250 on the gun and compressor, own it permanently and do lots of things with it for the rest of your life- like paint your house, air clean stuff, run other tools with it, etc.
If you have a special car or a collector car, plan on spending a lot of time sanding and re-sanding, and fine sanding, and polishing, and correcting your mistakes, and doing body work.
If you don’t have an extra $3000 sitting around, this may be your only choice- AND you can do it, and come up with an absolutely gorgeous job. I will show you how, and my methods come from THE BEST EXPERTS possible.
If you just have an old car and would rather do it yourself than spend $300 or $400 at the budget shops for a mediocre job that they will do, you can do it quickly and end up with a finish as good if not better than such shops, and spend a minimum amount of time doing it- although you will still need the materials and equipment you don’t already own, and a place to do it.
You can get the download or DVD (it is dirt cheap), or just read through the basics on this page and get a good idea of what you will need to do.
Okay….you decide. No bull here. The best painting adventure to you!
