Compressors

[bdahlg68]

10 gal, 5.30 CFM at 90 PSI, Maximun pressure - 125 PSI

or

15 gal, 5.0 CFM at 90 PSI, Maximum pressure - 200 PSI

or both just too small?

Not painting cars and not a pro... but my current 2.6CFM at 90 PSI out of 5.5 gal just doesn't cut it. Seems if I double that, that is a big step. Looking to stay pretty quiet and both above units are below 80 dBA.

Does the extra pressure / gallons really help much?
