Air compressor and impact attachments info

[dss56]

Looking to buy an air compressor and impact wrench for general auto use. Also to use the compressor for a paint spray gun attachment. Any suggestion for the compressor type like psi and electric or gas. Type of impact wrench and what ever I might need.I see that Pep Boys has a 10 gallon compressor for sale $99. Will this be sufficient for the impact and spray gun. Its model UST #1110c in this weeks sale paper. again just using this on my car ant dodge truck. Also see on line that Lowes has a good line of compressors and attachments. Again looking for specs i might need for this.

thanks
