What is the minimum size of air compressor that I could get to use
for painting a car?It's because I have limited space and no garage.I
just have a shed in my back yard and a driveway,so space is at a premium.Thank You.

Its not really the size you need is the CFMS it puts out. I believe you need at least a 10 to 12 CFMs and at least a 60 gallon tank. You can get buy with less, but you will have shorter spray times.

depends on the guns air pressure and use, if you are using one that needs 50 lbs or more constant pressure that consumes X amount of air you need a compressor capable of keeping that, I had a friend who got away with a small 20 or 30 gallon tank and painted entire cars with that. he would just spray one tank of paint from his gun and by the time he had mixed and filled the next container it had built up enough pressure to spray that.

Just make sure you get a good dryer and some of those disposable water filters for your guns air supply or you will end up with fish eyes in your paint job.

Detroit iron rules all the rest are just toys.

Go with an upright. You can get a big enough compressor in a tight space that way.

Keep an I eye on the power requirements. I don't suppose you have 220V in the shed...

Do yourself a favor and get a belt driven compressor and don't go oil-less. They don't last, over heat and harder to get parts for.

One more down side to oil less, NOISE! Damn those things are loud.

"Rule of thumb" for Compressors: Always Get "The biggest" you can possibly AFFORD" ! anything" less" than a 60 gal - 6 HP, is pretty much a waste", and you will be sorry you didn't spring for a 7HP- 80 Gal. I've got 2- 60 gallon tanks" hooked together"r with 2- 6 HP Motors and twin compressors.
