I can't find the actual CFM specs anywhere. I saw on another thread a guy guessed it would be around 6-8 CFM. How important is it to get to this number?
Would this work ok?

I'm only spraying the underbody of 2 cars (about 1 gallon), and I don't mind if it takes a little longer. I really want to spend as close to $100 as possible, since I don't need a compressor very often.
What do you think?

Im not a hard core air expert... but just from owning my own setup for many years i'll tell you right now that more air is better than less air... 10 gallons of air is nothing depending on the tool.
If you can't maintain 6-8 CFM the spray gun might not operate correctly... as the pressure drops, so will the flow. You might get problems with the fluid not atomizing correctly, spattering, poor coverage or application... The biggest problem being consistency from constantly changing pressures & volume.
I would probably shop for at least a 20-30 gallon tank minimum.
That's the size I run and there are plenty of tools that I own that feel it could benefit from a bigger tank. Spray guns, grinders, and sanders top that list. Painting generally has very demanding air requirements.
The last place you want to cut corners on a setup that requires air, is the air...
Remember, you still need to budget for lines, fittings, pressure regulator, and dryer/drip-t for water collection/moisture management which is probably even more important when painting than running air tools ... The compressor and tank is only 1 part of the system.
