Re: what's the best air compressor for a car paint job?
Painting requires lots of air! I want my compressor to have a MINIMUM 10 gallons or more capacity and provide 6-7 CFM at 90 PSI. The duty rating should be at least 50%. Many compressor have a label on them showing what uses they are well suited for. Start with the gun, the air requirements are usually printed on the packaging, use those as minimums! Good luck!
Re: what's the best air compressor for a car paint job?
You will hear a variety of opinions on this subject...but I personally would recommend a compressor with at LEAST a 60 gallon tank with 5hp motor...you don't want to risk ruining a paint job because you didn't have enough air...bigger is always better! Bottom line, you will most likely be using air tools and sanders so you will want to have somewhere around 15psi @ 90 to get the job done. Good luck.

Here are a few things to check, you may have already checked some of these. Electricity...Compressors will run best with full 115Vot 15AMP/Or 220V electrical supply from a circuit, over the shortest electrical cord as possible.
Air Leaks..Place your ear close to the compressor and listen for air leaking, if you hear air that is not normal and means you have to locate and repair whatever it is that is leaking. Check the air unloader valve... The air unloader valve will blown out air when you turned off the compressor, that is normal. But it should not have air leaking out of it all of the time. If so then it is faulty and in need of repair/replacement.
Valves...If either the intake or exaust valves fail, breaks, or fails to seat, then your compressor will run 24 hours a day and never build up to the correct pressure for shut-off.
Gaskets...Check to see if your gaskets have failed. You could have a gasket failure between the pistons and you will never know it because it shows no external air leak. If this situation happens then the air will only cycle between cylinders and never build up the correct air pressure. One way to check the gasket is remove the air filter, then put your hand over the intake. Please take time to rate me Bud
Mine will not start unless the tank is empty, or when it is cold out. I need a min of 20 amps to run my little comp, no cords, has to be warm, Just a high voltage machine that needs to warm up the oil, once it gets going, it will run all day, but getting it going is a nightmare. I was on a job last winter in Georgia and they had a heater in one bathroom, with a compressor in there, I thought it was for us to warm up with, it was for the compressor, mine was in there later that day. Try it, If not, it could be the capacitor.
First get some teflon thread tape, for applying 2 or 3 tightly wrapped turns around the male threaded quick-disconnect adapters, threaded end on your air hose and compressor before installation.
Note: remember that the female quick-disconnect adapter is also a check valve that will only release air when a male quick-disconnect adapter is inserted, i.e. do not install a male quick-disconnect adapter directly to an air compressor outlet.
Note 2:Always remember to wear approved eye protection when operating air tools.
Start by installing the female quick-disconnect adapters on a male threaded end of the air hose and on to the outlet port on the air compressor tighten the connections with two open end wrench's. Then install the male quick-disconnect adapters to the other end of the hose, blow-gun tool, and the air chuck tool, (tighten as described above). The other implements in the kit (wire brush attachment, inflation needle, etc...) can be threaded in to the outlet port of the blow-gun as needed.
The operation of connecting quick-disconnects are as follows:
Grasp the tool in one hand, and with the other hand grasp the air line near the end leaving the thumb and fore finger free to operate the spring loaded outer release cylinder on the female quick-disconnect by pulling back on it. With the cylinder pulled back, insert the male quick-disconnect adapter in to the female quick-disconnect adapter, then release the thumb and fore finger from the outter release cylinder, thus locking the two together. check to be sure the lock has engaged by lightly pulling at the tool. Reversing this process will disengage the tool from the air line.
Hope this helps
Most air pressure regulator knobs work like a "child-proof" cap on a medicine vial. It has a spring inside that keeps it dis-engaged from the tooth like gears inside. To turn the knob you must first pull out or push in the knob. You should feel some resistance from the spring inside. As you pull, you will feel the knob seat into the "teeth" inside. Then you can turn the knob and change the air pressure supplied. Note: most air regulator valves work in the opposite manner of regular water valves. Turning the knob clockwise should increase the air pressure... counter clockwise should decrease the pressure.
I hope this solution will bring you success. Best Regards, Michael Mittelsdorf
Portable air compressors give flexibility to the job both inside and outside the working environment. They're powered by electric, gasoline or diesel engine. A larger portable air compressor often has its own carrying trailer with wheels and handles. You buy a compressor based on its horsepower, pounds per square inch (PSI) and cubic feet per minute (CFM). Choose a portable air compressor to make work quicker and easier. Figure the amount of power you need based on the type of job and air tools used. Know the cubic feet per minute (CFM), such as 5 CFM for small household tools and 10 CFM or more for wrenches or sanders. All air tools have these ratings. Select a gas- or electric-powered engine. Gas gives a higher reliability for frequent use and portability, but consider electric for enclosed areas for its lack of fumes. Pick an air tank based on amount of use time and tools. Large tanks are best for longer use with sanders or grinders and smaller tanks for less time, like wrenches and air hammers. Consider the pump type you need: belt for heavy use or direct-drive for light home use. The quieter belt-drive pump needs periodic oil changes. Buy an inexpensive, small electric portable air compressor for small jobs. These typically operate from a 12-volt power outlet and inflate a 14-inch tire in a few minutes. Get a 150 PSI, 120 volt motor pancake-type air compressor for home use. These light-use models typically carry two air couplers, allowing hook up of two air tools and adequate 25 feet or more air hose. Obtain a larger PSI portable air compressor for bigger jobs, like nailing, with longer continuous use capabilities.
Set up the pressure on the air compressor. First plug the air compressor in, then check the pressure. It should be between 90 and 110 pounds per square inch (PSI) for home use. If it is not in this range, turn the knob to the left to decrease the pressure and to the right to increase the pressure. Use the appropriate nail gun for the job. For example, to nail shoe molding to base boards, a standard finishing nail gun would be perfect. It holds any size nail between 5/8 inch and 2 inches. This nail gun could be used for many projects with great results. Check the gauge the nail gun takes before purchasing the nails for the gun. If you get the wrong gauge they will not fit in the gun. You can check this by looking at the information printed on the side of the nail gun next to the model number. You can also open the nail chamber for this information. Attach the nail gun to the air compressor. You can do this before or after you load the nails into the gun. Use the air compressor hose to attach to the bottom of the nail gun. It screws on much like the end of a hose. If you do not have the right size air hose, you can find one at your local hardware store.
Craftsmen often prefer a compressed air tool over an electric power tool for certain jobs. Drywall and trim work are both made easier and accomplished more quickly with pneumatic tools. The most commonly purchased compressed air tool duo for homeowners is the pneumatic drill and nail gun. If you are a homeowner shopping for compressed air tools, be sure you understand how different models work and how the power is supplied. Read the manufacturer’s directions for use and maintenance, and be sure to have the proper sized hoses, fittings, and air compressor.
