It appears it is time for a new compressor. I have been using an old Quincy QE-5 compressor with 80 gallon tank for years. It has finally played out. I have been looking, and I do not even really know where to begin. I am a single person shop that only does collision repair part time. Maybe 2 to 3 cars a month on average. What compressors would ya'll recommend for someone in my position? I want to make sure I have plenty of cfm for spraying (using a SATA 5000 RP) and running a sander. I think my gun uses 15.5 cfm.
