i think what he's saying is the stuff is super cheap and likely the tank is some kind of popcan material. get that thing up to pressure and you'd basically have a bomb. some things you can't cheap out on. a good compressor is one of them.

most spray guns have requirements for air (a certain psi and a certain cubic feet per minute.) you must be sure to purchase a compressor with a built in regulator (or purchase one separately) and also be sure to buy one capable of supplying said pressure/CFM.

I tried painting with one of those little pancake compressors. It was capable at running the gun, but it ran out of air quickly, causing the flow to be uneven after a few seconds of spraying. once the pressure was back up again it was good again.  :banghead: something with a larger reserve tank would have been better.

A cheap compressor can supply high psi for a short time.  However, even if it has a large tank or a reserve/remote tank, duty cycle comes in to play.  cheaper compressors and motors are not rated to run continuously, they would burn up.  the cost cutting is in the materials, gauge of wire, cooling fins, heat dissipation, etc.  These corners are cut and if you can even find the specs, you'll see something like 5 or 10% duty cycle listed.  that means the motor is rated/designed to be off 90% of the time and running 10%.  if you run it 100% for long enough it will break.  Cheap compressors are great for nailers, staplers, air ratchets, tools that have intermittent duty.  You need the real thing for spraying, sanders, DA's, and grinder/zizz wheels. 

I only have a consumer grade compressor, so no pneumatic powered spraying for me.

I did.  The first tank had multiple holes along the joint where they welded the motor bracket to the tank.  It sounded like 3 whistles every time there was air in it.  The second tank was worse.  I did not get a third tank.

    Like I say, Ive never looked at the H/f tanks...Yikes... Maybe stay away from those, Ive had good, big,small, expensive,and cheap ones... I feel that replacing it every few years of hard use is best, Instead of waiting for the death knock.
That said, cheap is what I do, Wal mart is where the last one came from (The biggest tank they had). Ive got no regets, and get
a nice life cycle from them. (Upgrade the hose to rubber)... Craftsman makes nice ones too, These get big however,
You only need a 20gal tank...Unless you plan to paint cars too.

I finshed off my 'how to' videos on this subject (located in my project thread)  here's the result.
