so im just snoopin around for a good air compressor hoping to get some good advice here. well im looking for somthing that can do basic automotive repairs at home using an impact wrench and air ratchet most of the times, might use it for home repair also for example nailing, etc. just wondering what advice you can give me for example 3.5 hp and 30 gallons and shuch, what would be a good setup at home. i also want to get a sand blaster from harbor freight and i know i have to run an air compressor with it, i need a compressor compatible with that also.
